Vedclass · Answer

(D) The frame $S_2$ is moving with a constant velocity $(5 \hat{i} + 10 \hat{j} \, m/s)$,which implies that its acceleration is zero. Therefore,$S_2$ is an inertial frame of reference.In an inertial frame,the net force acting on an object is given by Newton's second law: $F = ma$.The object is at rest in frame $S_1$,which has an acceleration $a = 5 \hat{i} + 10 \hat{j} \, m/s^2$.Since the object is at rest relative to $S_1$,it shares the same acceleration as $S_1$ with respect to an inertial observer.Given mass $m = 2 \, kg$ and acceleration $a = 5 \hat{i} + 10 \hat{j} \, m/s^2$,the net force is:$F = 2 	imes (5 \hat{i} + 10 \hat{j}) = 10 \hat{i} + 20 \hat{j} \, N$.
