1.	An iron ball of mass 150 g is attachedto one end of a string and rotatedhorizontally so that the iron ballmoves along a circle of radius 1m.ifthe speed is 8m/s then what is thecentripetal force acting on the ball?
Answer» EXPLANATION: It's given that the m(mass of IRON ball) = 150g velocity of the iron ball = 8 m/s radius of the circle = 1 cm CGS ( centimetres-grams-seconds) system, m (mass)= 150 kg v ( velocity) = 800 cm/s r (radius) = 1 cm we KNOW that, CENTRIPETAL force (Fc) = mv²/r substituting the values we get, $Fc = \frac{0.15 \times {8}^{2} }{0.01} \\ = \frac{0.15 \times 64}{0.01} \\ = \frac{9.6}{0.01} \\ = 960 \: N$ Thus, there's 960 N of centripetal force acting on the ball.

EXPLANATION:

It's given that the

m(mass of IRON ball) = 150g

velocity of the iron ball = 8 m/s

radius of the circle = 1 cm

CGS ( centimetres-grams-seconds) system,

m (mass)= 150 kg

v ( velocity) = 800 cm/s

r (radius) = 1 cm

we KNOW that,

CENTRIPETAL force (Fc) = mv²/r

substituting the values we get,

$Fc = \frac{0.15 \times {8}^{2} }{0.01} \\ = \frac{0.15 \times 64}{0.01} \\ = \frac{9.6}{0.01} \\ = 960 \: N$

Thus, there's 960 N of centripetal force acting on the ball.
