Question

1. A ball weighing 0.3 kg is whirling in a vertical circle of radius 1.5 m. The number of revolutions made by the ball per second is 5. Calculate
the tension in the string at the topmost point and at the lowermost point.​

Answer 1

Answer:

7.2 N

Explanation:

Mass of the stone m = 0.3 kg

Length of the string R = 1.5 m

Speed v = 6 m/s

Then,

T = mv^2/T = 0.3 x 6 x 6/1.5 = 7.2 N

Answer 2

Explanation:

hii u have answered my question wrong. I have got the right answer

quotient is m

and remainder is 1
