How much time does it take to perform 500J of work at a rate of 10W?

A

`20s`

B

`30s`

C

`40s`

D

`50s`

Verified by Experts

The correct Answer is:

D

Here, work to be perform, W = 500J
rate at which work is to be performed, i.e., power, P =10W
AS `P = (W)/(t), t =(W)/(P) = (500J)/(10W) = 50s`
