A solid sphere is rolling on a surface as shown in figure, with a translational velocity $v m s^{- 1}$ . If it is to climb the inclined surface continuing to roll without slipping, then minimum velocity for this to happen is

Options:

Answer:

Solution:

Minimum velocity for a body rolling without slipping $v = \frac{2 g h}{1 + \frac{K ^{2}}{R ^{2}}}$ For solid sphere, $\frac{K ^{2}}{R ^{2}} = \frac{2}{5}$ $∴ v = \frac{2 g h}{1 + \frac{K ^{2}}{R ^{2}}} = \frac{10}{7} g h$
