A particle travels along the arc of a circle of radius r.Its velocity depends on the arc coordinate l (distance measured from starting point along the circle) as V=[c.square root of l] ;where c is a constant.Find theangle A between the vectors of the total acceleration and velocity of the particle.1. tanA =2l/r 2. cosA =2l/r3. sinA=2l/r 4. cotA =2l/r
