Answer:
0.758 N
Explanation:
mass of ball, = 36 g = 0.036 kg
radius, r = 19 cm = 0.19 m
tangential velocity, v = 200 cm / s = 2 m /s
The tension is the string is equal to the centripetal force acting on the ball.
The centripetal force acting on the ball is given by


T = 0.758 N
Thus, the tension in the string is given by 0.758 N.
B. Barometer is used to measure atmospheric pressure.
