Q: A bob is whirled in a horizontal plane by means of a string with an initial speed of rpm. The tension in the string is T. If speed becomes 2 while keeping the same radius, the tension in the string be

T=m ^2 aligned & T^ =m (2 )^2 \\ & T^ =4 T aligned

Question 1

A particle moving with uniform speed in a circular path maintains:

Accepted Answer

A particle moving with uniform speed in a circular path maintains varying velocity and varying acceleration. It is because direction of both velocity as well as acceleration will change continuously.

Question 2

A bob is whirled in a horizontal plane by means of a string with an initial speed of rpm. The tension in the string is T. If speed becomes 2 while keeping the same radius, the tension in the string be

Accepted Answer

T=m ^2 aligned & T^ =m (2 )^2 \ & T^ =4 T aligned
