JEE Main 9 April 2024, Shift 2, Physics Q38

Question 38 of 90 in this shift, Physics question 8 of 30, Section A.

A satellite of

10^3

kg mass is revolving in circular orbit of radius

2R

. If

\frac{10^4R}{6}

J energy is supplied to the satellite, it would revolve in a new circular orbit of radius : (use

g=10\ \mathrm{m/s^2}

R

= radius of earth)

(1) $2.5\,R$
(2) $3\,R$
(3) $4\,R$
(4) $6\,R$ Official answer
