Gravitational field at the centre of a semicircle formed by a thin wire AB of mass m and length l is:
- \(\frac{G m}{\ell^{2}}\)along + x axis
- \(\frac{G m}{\pi \ell^{2}}\)along +y axis
- \(\frac{2 \pi G m}{\ell^{2}}\)along + x axis
- \(\frac{2 \pi G m}{\ell^{2}}\)along + y axis
Answer
(D) 2 G m ^ 2 along + y axis
