A stone of mass 10 g is being moved in a circle ofradius 50 cm with a uniform speed of 1 ms. Theacceleration of the stone is(a) Zero(b) 2 m/s(d) 0.5 m/s |

Answer» F = ( Centripetal Force ) v is the Tangential Velocity r is the Radius of circler = 50cm = 0.5 mv = 1m s⁻¹F = ma = mv² r ⁻¹a = v² r⁻¹ Therefore, Centripetal Acceleration = ( 1 )² / ( 0.5 ) = 2m s⁻² (b) is correct option |
