A satellite revolving in a circular equatorial orbit from west to east appears over a certain point on the equator every 8 hours therefore it’s period is A satellite revolving in a circular equatorial orbit from west to east appears over a certain point on the equator every 8 hours therefore it's period is September [...]

Two bodies, each of mass M, are kept fixed with a separation 2L. A particle of mass m is projected from the midpoint of the line joining their centres, perpendicular to the line. The gravitational constant is G. The correct statement is are kept fixed with a separation 2L. A particle of mass m is [...]

Two rings having masses M and 2M, respectively, having the same radius are placed coaxially as shown in the figure. If the mass distribution on both the rings is non-uniform, then the gravitational potential at point P is? having the same radius are placed coaxially as shown in the figure. If the mass distribution on [...]
