A body of mass ' $m$ ' attached at the end of a string is just completing the loop in a vertical circle. The apparent weight of the body at the lowest point in its path is ( $g =$ gravitational acceleration)

Options:

Answer:

Solution:

The tension at the lowest point is $T = \frac{mv ^{2}}{r} + mg$ To complete the vertical circle, the minimum velocity should be $v = 5 gr$ $∴ T R ∴ T = \frac{m ( 5 gr ) ^{2}}{r} + mg = 5 mg + mg = 6 mg$
