Question: A particle moves in a circle of radius 25 cm at two revolutions per second. The acceleration of the particle in m/s2 it’s [MNR 1991; UPSEAT 2000; DPMT 1999; RPET 2003; Pb. PET 2004]

Options:

A) π2

B) 8π2

C) 4π2

D) 2π2

Show Answer

Answer:

Correct Answer: C

Solution:

Since n=2 , ω=2π×2=4πrad/s2 So acceleration =ω2r

=(4π)2×25100m/s2=4π2
