A force of \( 10 \mathrm{~N} \) is applied on an object of mass \( 2 \mathrm{~kg} \) placed on a rough surface having coefficient of friction equal to \( 0.2 \). Work done by applied force in \( 4 \mathrm{~s} \) is
(a) \( 120 \mathrm{~J} \)
(b) \( 240 \mathrm{~J} \)
(c) \( 250 \mathrm{~J} \)
(d) \( 100 \mathrm{~J} \)
