Question
A car moving on a circular path of length 4π meter experiences a force of 6N towards the center of the path. If the mass of the car is 108 kg, the velocity of the car is
Options
A.0.66ms-1
B.0.33ms-1
C.0.77ms-1
D.0.99ms-1
Solution
Here, F = 6N
C = 4π ⇒ 2π = 4π
or, r = 2m
m = 108 kg, v = ?
we have, F =
or v2 =
∴ v =
ms-1 = 0.33ms-1
C = 4π ⇒ 2π = 4π
or, r = 2m
m = 108 kg, v = ?
we have, F =
or v2 =
∴ v =
ms-1 = 0.33ms-1Create a free account to view solution
