A mass of 100 gm is tied to one end of a string 2m long The body is revolving in a horizontal circle making an maximum of 200 revolutions per min The other end of the string is fixed at the centre of the circle of revolution The max tension that the string can bear

Dear pallvi

m =200 gm =.2kg

r = 2m

ω=200 rev/min  =20 ∏/3 rad /sec

 centrifugal force F = mω²r

                           = .2 * (20 ∏/3)² * 2

                           =175.45 N
