Question

if m1=2kg and m2=4kg and the distance between them is 2×10^-6m, then force between two masses is _N2×10^-6m​

Answer 1

Given:

m1=2kg and m2=4kg and the distance between them is 2×10^-6m

To find:

The force between two masses

Solution:

We have the formula to calculate the force between 2 masses, given by,

$F = \dfrac{G \times m_1 \times m_2}{d^2}$

where, F = force between the 2 masses

m₁ = mass of the first object

m₂ = mass of the second object

G = gravitational constant

d = distance between the masses.

From given, we have,

m₁ = 2 kg

m₂ = 4 kg

d = 2 × 10^-6 m

G = 6.67 × 10^-11 m³/kg s²

$F = \dfrac{6.67 \times 10^{-11} \times 2 \times 4}{(2 \times 10^{-6})^2}$

∴ F = 133.4 N
