Question

If two bodies of masses 2000 kg and 4000 kg are separated by a distance of 10m the gravitational force attraction between them is a)6.67×10‐¹¹N
b)48.85×10^7N
c)53.36N
d)53.36×10^‐7N ​

Answer 1

Answer:

d)53.36×10⁻⁷N ​

Step-by-step explanation:

The formula for gravitational force between two bodies is given by

F = G (Mm/r²)

Where,

F = gravitational force ( we are asked to find this)

G = gravitational constant = 6.674 x 10⁻¹¹

M = mass of one of the bodies = 4000 kg

m = mass of the the other body = 2000 kg

r = distance between the two bodies = 10m

substituting the above values into the equation:

F = G (Mm/r²)

= (6.674 x 10⁻¹¹) (4000)(2000) / (10²)

= 5.339 x 10⁻⁶

= 53.39 x 10⁻⁷  Newtons

The closest answer to this is d
