Question

Cn u plz gv explaination 2 d solutions steps by steps briefly?Cz i really dnt understand hw 2 apply d formula wen i revise it nw. Much appreciated. [g=10 m/s^2 ] a fixed wedge whose smooth sloping face is inclined at 30 degree to the horizontal. A particle A, of mass 2 kg, rests on the sloping face of the wedge. A light inextensible string, passes over a smooth pulley at the top of the wedge & connects A to a particle B,of mass 3kg, which hangs freely. The sloping part of the string is parallel to a line of greatest slope,is applied to A. Assuming that A has not reached the bottom of the slope & B has not reached the pulley, calculate (a) the tension in the string, (b) the work done by the 25 N force while the speed of the particles increases from 1 m/s to 3 m/s.Ans: (a)33 N (b)100J
