A body of mass 5 kg is being pulled up along a rouch inclined plane with an acceleration of `5 cm s^(-2)` by means of a weightless string running parallel to the plane. If the inclination of the plane be `45^(@)` to the horizontal and the coefficient of friction between the body and the plane be 0.3, find the pull in the string. `(g = 9.8 ms^(-2))`.
