A rope 1 cm in diameter breaks, if the tension in it exceeds 500 N. The maximum tension that may be given to similar rope of diameter 3 cm is

A

2000 N

B

1000 N

C

500 N

D

250 N

Text Solution

Verified by Experts

The correct Answer is:
A
`(F_(2))/(F_(1))=((r_(2))/(r_(1)))^(2)=(4)/(1)`
`F_(2)=4F_(1)=4xx500=2000N`.
