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 : |
|
Answer» `(G)/(sqrt(l^(2)-1))` `mg sin theta= ma costheta` `a = g tan theta( :.sin theta =(1)/(l))` `gxx(1)/(sqrt(l^(2)-1))=(g)/(sqrt(l^(2)-1))` (a) is the choice.
