A car is moving in a circular horizontal track of radius 10 ~m the roof of the car by a light wire of length 1.0 ~m . The angle made by the wire with the vertical is:

Step-by-step solution

From the question v=10 ~m / s , r =10 m , g =10 ~m / s ^2 If = angle made by wire with vertical then aligned & = V^2 r g & = 10 10 10 10 =1 =1 = ⁻¹ & ( i )= 4 aligned
