The horizontal acceleration that should be given to a smooth inclined plane of angle sin–1(1/l) to keep an object stationary on the plane relative to the inclined plane is –

A

g/l2−1g/\sqrt{\mathcal{l}^{2} - 1}

B

gl2−1g\sqrt{\mathcal{l}^{2} - 1}

C

l2−1/g\sqrt{\mathcal{l}^{2} - 1/g}

D

g/l2+1g/\sqrt{\mathcal{l}^{2} + 1}
