A block of mass \( 4 \mathrm{~kg} \) is resting on a horizontal table and a force of \( 10 \mathrm{~N} \) is applied on it in the horizontal direction. The coefficient of kinetic friction between the block and the table is \( 0.1 \). The work done in \( \sqrt{20} \mathrm{~s} \) :
(A) By the applied force is \( 150 \mathrm{~J} \)
(B) By the frictional force is \( 60 \mathrm{~J} \)
(C) By the applied force and the net force are \( 150 \mathrm{~J} \) and \( 90 \mathrm{~J} \) respectively
(D) All are correct
