Physics - Circular Motion Question with Solution | TestHub

A very small ball of mass ' $\mathrm{m}=5{\mathrm{kg}}^{\prime }$ is suspended from point A through an inextensible thread of length $\ell =4\mathrm{m}$. It lies on the surface of a fixed smooth sphere of radius $\mathrm{R}=3\mathrm{m}$. The ball is moving in a circular path with a constant speed $\mathrm{v}=1\mathrm{m}/\mathrm{s}$ so that it always maintains contact with the surface of sphere. Find the normal reaction 'N' (in Newton) acting on the ball. Fill $\frac{3\mathrm{N}}{17}$ in OMR sheet. $\left(\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right)$
