In the figure shown all the surfaces are frictionless, and
\( \mathrm{P} \)
mass of the block, \( m=1 \mathrm{~kg} \). The block and wedge are held initially at rest. Now wedge is given a horizontal acceleration of \( 10 \mathrm{~m} / \mathrm{s}^{2} \) by applying a force on the wedge, so that the block does not slip on the wedge. Then work done by the normal force in ground frame on the block in \( \sqrt{3} \) seconds is:
(1) \( 30 \mathrm{~J} \)
(3) \( 150 \mathrm{~J} \)
(2) \( 60 \mathrm{~J} \)
W.
\( \rightarrow 10 \mathrm{~m} / \mathrm{s}^{2} \)
(3) \( 150 \mathrm{~J} \)
(4) \( 100 \sqrt{3} J \)
