Unbalanced forces cause accelerations.
In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down. To verify if the forces acting upon an object are balanced or unbalanced, an analysis must be conducted to verify what forces are acting upon the object and in what direction. If two individual forces are of equivalent magnitude and opposite direction, the forces are balanced. An object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of euqivalent magnitude and in the opposite direction
The potential because of a continuous charge distribution is the sum of potentials of all the infinitesimal charge elements in which the distribution may be separated i.e.,
In whole analog to the work energy theorem for the translator motion, it might be stated for rotational motion as: Δ W rot = K rot The net rotational work given by the force
Motion of an object in a plane is known two dimensional (2-D) motions. For 2-D motion acceleration or velocity can be defined by two elements in any two mutually perpendicular dire

50 gm of an optically active substance is dissolved in 100 ml of water. A plane polarised light, when passing through 30 cm of the solution, suffers a rotation of 390 in it's plane
INSTANTANEOUS VELOCITY: The velocity of a body at a certain instant of time is known as instantaneous velocity.
