Question

A small body of mass 0.4kg perform vertical circular motion of a string 0.6m long with constant speed of 3m/s its makes an angle of 30degree with the vertical calculate tension in the string​

Answer 1

Answer:

Max tension in the string when string at the bottom of the vertical ciecle in which both centrifugal ang gravitational force is acting in the same direction as shown in the fiqure

T=mw

×0.04+10×10=10+100=110N

Hence the correct option is c
