1.	Consider two satellites A and B. Both move around the earth in the same orbit but the mass of B is twice that of the mass of A.(a) Orbital speeds of A and B are equal(b) The orbital speed of A is twice that of B(c) The orbital speed of B is twice that of A(d) The kinetic energy of both A and B are equalThis question was addressed to me by my school teacher while I was bunking the class.This question is from Gravitation in section Gravitation of Physics – Class 11
Answer» Right choice is (a) Orbital speeds of A and B are equal The explanation is: SINCE orbital velocities are independent of the mass of SATELLITES and only depends on the radius of orbits, they are equal for both A and B. The kinetic energy of a satellite depends on the mass of the satellite. HENCE, it differs for satellite A and B.
