Assertion: For looping a vertical loop of radius,

r

the minimum velocity at point should be

\sqrt{5 g r}

.

Reason: In this even the velocity at the highest point will be zero.

View answer and explanation

Correct option: C

If assertion is true but reason is false.

The correct answer is C. The assertion is true because the minimum velocity at the lowest point to complete a vertical loop is

\sqrt{5gr}

. The reason is false because the velocity at the highest point is not zero, it is

\sqrt{gr}

.

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
