If a particle of mass m start from A along curved circular path
shown in figure with constant tangential acceleration a, then net force
at B on the particle has the magnitude

AzeroB[IMAGE] m a
A, B

Show answer and solution▾

Fnet = matotal = [IMAGE] at = a
ac = [IMAGE] v2 = 0 + 2a[IMAGE] ⇒ ac =[IMAGE] TOPIC: CIRCULAR MOTION
