Assertion : Two satellites of mass `m_(1)& m_(2)(m_(1) gt m_(2))` are going around the earth in orbit of raddi s ` r_(1) and r_(2)(r_(1) gt r_(2))` .
Reason : They will have same velocity .

Options

A. If both the assertion and reason are true statement and reason is correct explanation of the assertion .
B. If both the assertion and reason are true statement but reason is not a correct explanation of the assertion .
C. If the assertion is true but the reason is a false statement.
D. If both assertion and reason are false statements.

Answer

C

Explanation

`(GM_(e)M)/(r^(2))=(mv^(2))/(r)`
`implies v=sqrt((Gm_(e))/(r))`
`:. (v_(1))/(v_(2))=sqrt((r_(2))/(r_(1))` Since ` r_(1) gt r_(2), v_(2) gt v_(1)`
