    Initially a rectangular coil with length vertical is moving out with constant velocity ' vv ' in a constant magnetic field ' BB ' towards right. Now the same coil is rotated through 90∘90^{\circ} in same plane in same magnetic field BB and the coil is moving with same velocity vv. The magnitude of induced e.m.f. is now

    Two charges q1q_1 and q2q_2 are separated by a distance of 30cm. A third charge q3q_3 initially at point C is shown in figure, is moved along the circular path of radius 40 cm from C to D. If the difference in potential energy due to movement of q3q_3 from C to D is q3k/4πϵ0q_3k/4\pi\epsilon_0, the value of K is (ϵ0\epsilon_0 = permittivity of free space)

    The weights of an object are measured in a coal mine of depth h1h_{1}, then at sea level of height h2h_{2} and lastly at the top of a mountain of height h3h_{3} as W1,W2W_{1}, W_{2} and W3W_{3} respectively. Which one of the following relation is correct? [h1≪R,h3≫h2=R,R=h_{1} \ll R, h_{3} \gg h_{2} = R, R = radius of the earth]
