If the unit of length and force be increased four times, then the unit of energy is

A

16 times

B

8 times

C

2 times

D

4 times

Text Solution

Verified by Experts

The correct Answer is:
A
Joule=(Newton)(Metre)=`("4 Newton")/(4)xx("4 Metre")/(4)`
`=("Joules")/(16)`
Hence 1 Joules=16 joule(Joules is new unit of energy)
