Question

A 1 kg stone is tied to 1 m long string and is whirled in vertical circle at constant speed of 4 m/s. The tension in the string is 26 n when the stone is at

Answer 1

Answer:

Top of the circle

Explanation:

First calculate Fc(centripetal force) i.e mv^2/r which = 16N

Then T<Fc

So, T + mg = Fc

6 + 1 × 10 = 16

This is possible at top most point hence the answer is " at the top ".
