Question

Figure shows the variation of kinetic energy, potential energy and total energy as a function of the radius of a body in circular motion. Then

• A. A, B, C represent total energy, kinetic energy and potential energy respectively.
• B. A, B, C represent kinetic energy, potential energy and total energy respectively.
• C. A, B, C represent kinetic energy, total energy and potential energy respectively.
• D. A, B, C represent potential energy, kinetic energy and total energy respectively.

Answer 1

The correct option is C A, B, C represent kinetic energy, total energy and potential energy respectively.

$P.E=\frac{-GMm}{r}K.E=\frac{1}{2}m{v_0}^2=\frac{GMm}{2r}T.E=P.E+K.E=\frac{-GMm}{2r}So,\left(T.E\right|=\left(K.E\right|and\left(P.E\right|>\left(T.E\right|$
