Answer:

Explanation:
For pendulum A: Length = L and gravity = g
The frequency of pendulum A is given by

Here, f is the frequency, L be the length
... (1)
For pendulum B: Length = 2L, gravity = g
The frequency of pendulum B is given by
.... (2)
Divide equation (1) by (2)

Answer:
F=G(m1m2)/Rsquare if radius is given
F=G(m1m2)/dsquare if distance is given
where,
f =gravitational force
G =gravitational constant
m1=mass of one object
m2=mass of another object
d=distance between two object from their center r=radius of earth/planet
