### Sample Questions

Question 1
In an a.c. circuit the voltage applied is E = E0 sinω t. The resulting current in the circuit is I = I0 sin (ωt -π/2) . The power consumption in the circuit is given by
 P√2 E0I0 P = E0I0/2 P = zero P = E0I0/√2
Question 2
A point mass oscillates along the x-axis according to the law x = x0 cos (ωt − π/4). If the acceleration of the particle is written as a = A cos(ωt + δ)
 A = x0 ω2 , δ = −π/4 A = x0 ω2, δ = 3π/4 A = x0 ω2 , δ = −π/4 A = x0 , δ= −π/4
Question 3
A parallel plate condenser with a dielectric of dielectric constant K between the plates has a capacity C and is charged to a potential V volts. The dielectric slab is slowly removed from between the plates and then reinserted. The net work done by the system in this process is
 (K - 1)CV2 (1/2)(K - 1)CV2 CV2 (K - 1)/K zero
Question 4
A particle of mass m executes simple harmonic motion with amplitude ‘a’ and frequency ‘ν’. The average kinetic energy during its motion from the position of equilibrium to the end is
 4 π2ma2v2 2 π2ma2v2 π2ma2v2 (1/4) π2ma2v2
Question 5
In a Young’s double slit experiment the intensity at a point where the path difference is λ/6 ( λ being the wavelength of the light used) is I. If I0 denotes the maximum intensity, I/I0 is equal to
 41337 1/√2 41276 √3/2
Question 6
A particle is projected at 60° to the horizontal with a kinetic energy K. The kinetic energy at the highest point is
 K/2 K/4 K zero
Question 7
A 2 kg block slides on a horizontal floor with a speed of 4 m/s. It strikes a uncompressed spring,and compresses it till the block is motionless. The kinetic friction force is 15 N and spring constantis 10,000. N/m. The spring compresses by
 11.0 cm 2.5 cm 8.5 cm 5.5 cm
Question 8
Angular momentum of the particle rotating with a central force is constant due to
 Constant Force Constant linear momentum Constant Torque Zero Torque
Question 9
A circular disc of radius R is removed from a bigger circular disc of radius 2R such that the circumferences of the discs coincide. The centre of mass of the new disc is α /R from the centre of the bigger disc. The value of  α is
 1/4 1/2 1/6 1/3
Question 10
If gE and gm are the accelerations due to gravity on the surfaces of the earth and the moon respectively and if Millikan’s oil drop experiment could be performed on the two surfaces, one willfind the ratio (electronic charge on the moon) /(electronic charge on the earth) to be
 0 gE/gM 1 gM/gE
