Question

A body of mass 10 kg tied to a string which is fixed at one end is given a
velocity of 10 ms at the bottom so that it is whirled in a vertical circle
length of the string is 2 m. (g = 10 ms 2)​

Answer 1

Answer 2

Answer:

Tension in the string = 500 N

Explanation:

In the question,

Mass of the body, m = 10 kg

Velocity, v = 10 m/s

Length of the string = 2 m

So,

To calculate the maximum tension in the string, T.

The maximum tension is given by the centrifugal force acting on the mass because of the whirling of the mass in the circular motion.

So,

$Centrifugal\ force,F=\frac{mv^{2}}{r}$

So,

$T=\frac{mv^{2}}{r}\\T=\frac{(10)(10)^{2}}{2}\\T=500\ N$

Therefore, the tension in the string is 500 N.
