Question

A ball of mass 'm" is rotated in a vertical circle with constant speed. The difference in tension at the
top and bottom would be
1) 6 mg
2) 5 mg
3) 2 mg
4) mg​

Answer 1

Answer:

HELLO HERE IS YOUR ANSWER.

ITS FIRST OPTION i.e 6mg.

Explanation:

since tension at top point is 0.

Answer 2

Answer:

1) 6mg

Explanation:

Mass of ball=m

Let constant speed of ball=v

We have to find the difference in tension at the top and bottom .

Tension at top =0

Tension at bottom=$T_{top}$+6mg

Substitute the value then we get

Tension at bottom=6mg

Difference between tension at top and bottom =6mg-0=6mg

Answer:1) 6mg
