A sphere is accelerated upwards with the help of a cord whose braking strength is five times its weight. The maximum acceleration with which the sphere can move up without cord breaking is :-

A

g

B

3g

C

2g

D

4g

Text Solution

Verified by Experts

The correct Answer is:
B
T = m(g+a)
Since , T = 4mg
`rArr cancel(m) = cancel(m)(g + a)`
`rArr a = 3g`
