A large magnet of length 25 cm is broken into two pieces of length 15 cm and 10 cm respectively. The pole strengths of the two pieces will be in the ratio of

A

`1 : 1`

B

`3 : 2`

C

`2 : 3`

D

`2 : 1`

Text Solution

Verified by Experts

The correct Answer is:
A
When it is cut into two pieces of length 15 and 10 cm, pole strength remains the same.
Hence `m_(1)/m_(2)=1/1`
