A sphere is accelerated upwards with the help of a cord whose breaking strength is five times its weight. The maximum acceleration with which the sphere can move up without cord breaking is
Text Solution
Verified by ExpertsThe correct answer is:
A
Tension in the cord = m (g + a) and breaking strength = 5 mg
For critical condition 
⇒ ⇒ 
This is the maximum acceleration with which the sphere can move up with cord breaking.
