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

`10^(5) J`

B

`10^(4) J`

C

`10^(6) J`

D

`10^(3) J`

Text Solution

Verified by Experts

The correct Answer is:
A
`W = F_(s) cos theta = 200 xx 1000 xx (1)/(2) = 10^(5) J`
