A block of mass 3 kg rests on a horizontal frictionless xy-plane. What would be the acceleration of the block if it is subjected to two forces as shown in figure?

Horizontal component of 10 N is10 cos60° i. e. ,10 1/2Nor 5 N. It is balanced y 5 N force along x-axis.Y-component of 10 N force is 10 sin60 N.i.e., 10×32N or 53Nay=53N3kg=5ms−2
