d
a block of mass m moving on a circular path of radius R with constant tangettial acceleration at,the surface is rough(coefficient of friction is μ).
Find the speed of the block at which it will leave the circular path
a)√μgr
b)[(μ2g2+at2)R2,friction towards the center
c)[(μ2g2+at2)R2,friction not towards the center
D)b0[(μ2g2-at2)R2,friction not towards the center
