Question

The period of moons rotation around the earth is nearly 29 days. If moons mass were 2 fold its present value and all other things remained unchanged, the period of moons rotation would be nearly: (A)  29√2 days  (B)  (29/√2) days  (C)  29× 2 days  (D)  29 days

Time period, T=2π √( (l/g) ) is independent of mass of revolving body.

Q. The period of moons rotation around the earth is nearly 29 days. If moons mass were 2 fold its present value and all other things remained unchanged, the period of moons rotation would be nearly:

$292 d a ys$

$\frac{29}{2} d a ys$

$29 \times 2 d a ys$

$29 d a ys$

$\frac{29}{2} d a ys$

Time period, $T = 2 π (\frac{l}{g})$ is independent of mass of revolving body.

29×2days

29days

229​days

Time period, T=2π(gl​)​ is independent of mass of revolving body.

$292 d a ys$

$\frac{29}{2} d a ys$

$29 \times 2 d a ys$

$29 d a ys$

$\frac{29}{2} d a ys$

Time period, $T = 2 π (\frac{l}{g})$ is independent of mass of revolving body.
