Question

An object with a mass of 0.5 kilogram is swung by a string in a horizontal circle of radius 1 meter at a speed of 2 meters per second. The magnitude of the force on the mass is

Answer 1

$m=0.5Kg$

$v=2m/s$

$r=1m$

$Force=mass\times\frac{(velocity)^2}{radius}$

$F=0.5\times\frac{(2)^2}{1}$

$F=2N.$
