Question

if the speed o an object in uniform circular motion is doubled and the radius remains constant then the centripetal acceleration increases by a factor of

Answer 1

\[F _{c} = mv ^{2}/r\]

Answer 2

if speed is doubled means 2V then
\[F = m (2V)^{2}/r \]

Answer 3

\[F = 4mv ^{2}/r\]

Answer 4

F = ma = 4mv^2/r
So acceleration increases by a factor of 4 .
