QN0035193

A body of mass is whirled in a vertical circle making . If the radius of the circle is , then tension in the string when the body is at the top of the circle, is

(A)
(B)
(C)
(D)

Correct Answer: A

Explanation:

Given : Mass (m)

Its frequency

Radius . We know that linear velocity of the body

Therefore, tension in the string when the body is at the top of the circle (T)

QN0035194

A bucket tied at the end of a long string is whirled in a vertical circle with constant speed. What should be the minimum speed so that the water from the bucket does not spill when the bucket is at the highest position?

(A)
(B)
(C)
.
(D)
None of these

Correct Answer: A

Explanation:

Since water does not fall down, therefore the velocity of revolution should be just sufficient to provide centripetal acceleration at the top of vertical circle. So,
