Two bodies of masses 2kg and 3kg are connected by a metal wire of cross section 0.04 `mm^(2)`. Breaking stress of metal wire is 2.5 Gpa. The maximum force F that can be applied to 3kg block so that wire does not break is :

A

100N

B

150N

C

200N

D

250N

Text Solution

Verified by Experts

The correct Answer is:
D
`F-T=3a`
`T=2a`
`T=2.5xx10^(9)xx4xx10^(-8)`
`T=100N`
`T=2a`
`100=2a`
`a=50N`
`F=5xx50`
`F=250N`
