Questions
A satellite is launched into a circular orbit of radius R around the earth. A second satellite is launched into an orbit of radius (1.01)R. The period of the second satellite is larger than that of the first one by approximately
detailed solution
Correct option is C
In the problem, the orbital radius is increased by 1%Time period of satellite, T∝r3/2Percentage change in time period=32(% change in orbital radius )=32(1%)=1.5%Similar Questions
In the following four periods
(i) Time of revolution of a satellite just above the earth’s surface
(ii) Period of oscillation of mass inside the tunnel bored along the diameter of the earth
(iii) Period of simple pendulum having a length equal to the earth’s radius in a uniform field of 9.8 N/kg
(iv) Period of an infinite length simple pendulum in the earth’s real gravitational field
