Answer:
122444 Kg
Explanation:
Using the formula for gravitational force;
F= Gm1m2/r^2
Given that
G = constant of gravitation = 6.67 × 10−11 newton-metre2-kilogram−2.
m1 and m2 = the masses
r= distance of separation
Note that the question specifically mentioned that the masses are identical
so m1=m2 = m^2
F= Gm^2/r^2
Fr^2 = Gm^2
m^2 = Fr^2/G
m^2 = 1 × 1^2/6.67 × 10−11:
m =√ 6.67 × 10−11
m= 122444 Kg
