Earth is moving around the sun in an elliptical orbit as shown. The ratio of OB and OA is R. Then the ratio of speed Earth at A and B is:

Q. The earth moves around the Sun in an elliptical orbit as shown in Figure. The ratio OA/OB$=$x. The ratio of the speed of the earth at B to that at A is nearly.

Q. The earth moves around the sun in an elliptical orbit as shown in figure. The ratio $\frac{OA}{OB}=x$. The ratio of the speed of the earth at B to that at A is nearly

The Earth moves round the Sun in an elliptical orbit as shown in figure.

The ratio $\frac{OA}{OB}=x$, the ratio of the speed of the earth at B and at A is nearly

Q.

Two satellites are moving around the earth in circular orbits at height R and 3R respectively, R being the radius of the earth, the ratio of their kinetic energies is
