Questions
A particle moves in a circle of radius 25 cm at two revolutions per sec. The acceleration of the particle in is:
detailed solution
Correct option is C
r = 25 × 10-2 m, f = 2 /sec ω = 2πf= 4π rad/secAcceleration = ω2 r = (4π)2×25×10-2 = 16×25×10-2π2 m/s2 = 4π2 m/s2Talk to our academic expert!
