1) Two particles A and B are suspended from the same support. The particles carry negative charges with A having more value of negative charge than B. They diverge and reach equilibrium with A and A making angles alpha and beta with the vertical respectively
(a) alpha > beta (B) alpha < beta (c) alpha = beta (d) data is insufficient
2) in the system shown in the fig(attached with this mail), the wedge M and the block m are free to move without friction. when system is released, the acceleration of the block relative to the wedge
1. is equal to gsin(theta)
2. Is directed along the surface of the wedge
which of the above statements are true
a. 1 only b) 2 only c) both 1 and 2 d) none
3) In moving from A to B along an electric field line, the electric filed does 4.8 * 10 ^ -19 J of work on an electron in the filed illustrated in the fig(attached with the mail).
Is Vb - Va 3 or -3
