Problem

A block of mass

1 \text{ kg}

is pushed up a surface inclined to horizontal at an angle of

60^\circ

by a force of

10 \text{ N}

parallel to the inclined surface as shown in figure. When the block is pushed up by

10 \text{ m}

along inclined surface, the work done against frictional force is :

[g = 10 \text{ m/s}^2]
