A particle of mass 200g is attached to an ideal string of length 1.30 m whose upper end is fixed to ceiling. The particle is made to revolve in a horizontal circle of radius 50 cm. The tension in the string is `(g = 10 m/s^2)`

Text Solution

Verified by Experts

Moment of inertia of the particle `l = nr^(2)`
Given `m = 200 = 0.200 kg, r=2 cm = 0.20 m`
`l=mr^(2) =0.200 xx 0.20 = 0.04 kg m^(2)`
