Assertion : It we double the circular radius of a satellite, then its potential energy, kinetic energy and total mechanical energy will become half.
Reason : Orbital speed of a satellite.
`upsilon prop (1)/(sqrt(r )`
where, `r` is its radius of orbit.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explantion of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
`V = - (GMm)/(R)`, `K = (GMm)/(2r)`, `E = - (GMm)/(2r)`
and `V = sqrt((GM)/(R))`
