The power (P) of an engine lifting a mass of 100 kg upto a height of 10 m in 1 min is

A

P=163.3 W

B

P=9800 W

C

P=10000 W

D

P=5000 W

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `"Power"=("Work done")/("Time")`
Work done `=mgh=100xx9.8xx10`
Time =1 min=60 s
`:. " " P=(100xx9.8xx10)/(60)=163.3 W`
