According to Newton's law of gravitation, any particle of matter in the universe attracts any other with a force varying directly as the product of their masses and inversely as the square of the distance between them. It is expressed as

F = Gm1m2/r^2

where

G = gravitational constant and its value is G = 6.673 x 10^-11 Nm^2/kg^2

m1 and m2 are the masses of the bodies

r is the distance between the bodies

From the information given,

m1 = 1

m2 = 2

r = 2

By substituting these values into the formula,

F = (6.7 x 10^-11 x 1 x 2)/2^2

F = 33.5 x 10^- 12

F = 3.35 x 10^-11

The second option is correct
