A lawn roller is displaced through `1 km` using a force of `200 N` In a direction making an angle of `60^(@)` with the lawn .The work down is:

A body acted upon by a force of 50N is displaced through a distance of 10m in a direction making an angle of 60^(@) with the force. Calculate the work done by the force.

A body, acted upon by a force off 50N is displaced through a distance 10 meter in a direction making and angle to 60^(@) with the force. The work done by the force be

A body, acted upon by a force of 50N, is displaced through a distance 10m in direction making an angle of 60^(@) with the force. Find the work done by the force.

A body, acted upon by a force of 50N, is displaced through a distance 10m in direction making an angle of 60^(@) with the force. Find the work done by the force.

A gardener pushes a lawn roller through a distance of 20m. If he applies a force of 20 kg wt in a direction inclined at 60^(@) to the grounds, find the work done by him. Take g=9.8ms^(-2) .
