Question

If two point masses 1kg & 4kg are seperated by a distance of 2m. Magnitude of gravitational force exerted by 1kg on 4kg is ?

(A) G/4
(B) G
(C) G/2
(D) G/3

​

Answer 1

• F = G Newtons

Step-by-step explanation:

Given:

• Mass of 1st body =
  `1\:kg`
• Mass of 2nd body =
  `4\:kg`

To Find:

• Magnitude of gravitational force

Solution:

Here, we have a formula

• 
  `F=(G.M_(1).M_(2))/(r^(2))`

Substituting the values

`\implies\:\:F = (G(1)(4))/(2^(2))`

`\implies\:\:F = (4G)/(4)`

`\implies\:\:F = \frac{\cancel{4}G}{\cancel{4}}`

`\implies\:\:\red{F = G}`

Know More:

The applied formula for the above solution is

`{\boxed{F_(G)=(G.M_(1).M_(2))/(r^(2))}}`

where,

• F
  `_(G)` = Gravitational force
• G = Gravitational constant
• M
  `_(1)` = mass of 1st body
• M
  `_(2)` = mass of 2nd body
• r = distance between two bodies
