In th egiven figure,`a = 15 m//s^(2)` represents the total acceleration of particle moving in the clockwise direction in a circle of radius `R = 2.5 m` at a given instant of time. If square of speed of the particle is `(75 sqrt3)/(n) m^(2)//s^(2)`. Then write the value of n.

Text Solution

Verified by Experts

The correct Answer is:
4
`15 cos 30^(@) = a_(c ) = (v^(2))/(R )`
`v^(2) = (75 sqrt3)/(4)`
