A body weighing 0.5 kg tied to a string ...

A body weighing 0.5 kg tied to a string is projected with a velocity of `10 ms^(-1)`. The body starts whirling in a vertical circle. If the radius of circle is 0.8 m, find the tension in the string when the body is (i) at the lop of the circle and (ii) at the bottom of the circle.
