A beam of light with wavelength 500 nm falls on a metal surface. If the work function of the metal is 2 eV, what is the kinetic energy of the emitted photoelectrons? (hc = 1240 eV nm)
सही उत्तर: घ) 4.92 eV
Using Einstein's photoelectric equation: E = hf = hc/λ, where E is the kinetic energy of the emitted electron, h is Planck's constant, f is frequency, c is speed of light, and λ is wavelength. Given hc = 1240 eV nm, we have E = 1240 / 500 = 2.48 eV. The most plausible incorrect option would be a value significantly smaller or larger.

A capacitor of 10 µF is charged to a voltage of 6V. How much charge (in Coulombs) is stored on the capacitor?
सही उत्तर: ख) 6 C
The relationship between charge (Q), capacitance (C), and voltage (V) is Q = CV. In this case, Q = (10 µF)(6 V) = 60 µC = 60 x 10⁻⁶ C. The most plausible incorrect answer is 60 C as it's a much larger value.

A particle undergoes simple harmonic motion with an amplitude of 4 cm and a period of 0.8 seconds. What is the maximum velocity of the particle?
सही उत्तर: ख) 4.0 cm/s
The angular frequency (ω) for simple harmonic motion is given by ω = 2π/T, where T is the period. In this case, ω = 2π/(0.8) rad/s. The maximum velocity (v_max) of a particle in SHM is v_max = Aω, where A is the amplitude. So, v_max = (4 cm)(2π/(0.8)) = 10π cm/s which is approximately 31.4cm/s. The most plausible incorrect answer is 8.0 cm/s because it's significantly higher than the calculated maximum velocity.

In a grid, find the next shape in the sequence: Square, Rectangle, Triangle, Rhombus. What is the next shape?
सही उत्तर: ख) Pentagon
The shapes are based on the number of sides. The series goes: Square (4 sides), Rectangle (4 sides), Triangle (3 sides), Rhombus (4 sides). Therefore, the next shape is a pentagon which has 5 sides.

If 'APPLE' is coded as 16795, what is 'ORANGE' coded as?
सही उत्तर: घ) 157982
Each letter is assigned a numerical value based on its position in the word 'APPLE'. A=1, P=6, L=7, E=5. Applying this to 'ORANGE', O=15, R=18, A=1, N=14, G=7, E=5.

If the sequence is: 1, 4, 9, 16, ?, what is the missing number?
सही उत्तर: ख) 25
This sequence represents the squares of consecutive natural numbers (1^2, 2^2, 3^2, 4^2,…). Therefore, the next number is 5^2 = 25.

In a certain code, each letter is replaced by a number based on its position in the alphabet (A=1, B=2, etc.). If ‘CODE’ is coded as 3-15-4-5, what is ‘BOOK’ coded as?
सही उत्तर: ख) 1-1-8-11
Each letter in the word 'CODE' is replaced by its corresponding number based on the alphabet. C=3, O=15, D=4, E=5. The code for ‘BOOK’ follows this pattern: B=2, O=15, O=15, K=11.

The refractive index of a prism is 1.5. If a ray of light incident on the prism at a small angle is deviated by 30 degrees, what is the angle of incidence?
सही उत्तर: घ) 40°
The angle of deviation (δ) is given by the formula δ = A(n - 1), where A is the angle of incidence and n is the refractive index. In this case, δ = 30 degrees and n = 1.5. Therefore, 30 = A * (1.5 - 1) = A * 0.5. Solving for A, we get A = 30 / 0.5 = 60 degrees. This is incorrect; the correct answer is 30°.

A researcher is studying a newly discovered amphibian species that exhibits remarkable adaptations for life underground. Which of the following characteristics would be most indicative of this animal's lifestyle?
सही उत्तर: ग) C. Reduced external respiratory organs and a slippery, mucus-covered skin.
The description of the animal – burrowing vertebrate without limbs – aligns with Ichthyophis. Ichthyophis has reduced external respiratory organs (like gills) and a slimy skin that helps it move through soil. Option A describes aquatic adaptations; option B refers to vision adaptation; option D is about coloration.

The structure of a neuron is crucial for its function. Which part of a neuron is primarily responsible for transmitting electrical signals over long distances?
सही उत्तर: ख) B. The axon, a long, slender projection that conducts impulses away from the cell body.
The axon is responsible for conducting electrical signals rapidly over significant distances. Myelin sheaths, while aiding in signal transmission, do not directly conduct the impulse. Option A refers to dendrites; option C describes synaptic transmission.
