Question

If a particle moves in a circle under inverse square field the radius 'r' of the circle is related to the time taken for one complete rotation 'T' is : 'l crf ~"1iIf.t ~ i'i ~ '11: 'Ifd~n", ~ l ~ 'r' :r m ~ : (1) raT (2) r2 aT (3) r' a T' (4) r' a T'

Answer 1

hey use these 2 formulas for such qstions. They save a lot of time as smtimes force may b given proportional to sm other power of radius. hope u like it!!
