A body of mas 1 kg is taken from infinilty to a point P. When the body reaches that point, it has a speed of 2m^(-1). The work done by coservative force is -5J. Which of the following is true (assuming non conservation and pseudo-forces to be absent).

Answer»

<P>Work done by applied force is +7J.
The TOTAL energy possessed by the body at P is+7J
The potential energy possessed by the body at P is +5J
Work done by all forces TOGETHER is EQUAL to the change in kinetic energy.
