How much work is done by a force of 10 N in moving an object through a distance of 1 m in the direction of the force ?
A
`20 J`
B
`100 J`
C
`15 J`
D
`10 J`
Text Solution
Verified by Experts
The correct Answer is:
D
The work done is calculated by using the formula : `W = F xx s` Here, Force, F = 10 N And, Distance, s = 1 m So, Work done, `W = 10 xx 1 J` = 10 J Thus, the work done is 10 joules.
