Question

Two particles of mass 2kg and 4kg are placed at a seperation of 20cm what is the gravitational force between them
plz answer this correctly i will mark u as brainliest

Answer 1

Answer:

1.334x10^-8  (1.33 x 10 to the power -8)

Step-by-step explanation:

20 cm= 0.2 m

We know,

F=GMm/r^2

=(6.674x10^-11 x 2 x 4) / (0.2)^2

=1.334x10^-8

Answer 2

Answer:

We have been give two particles of mass 2 kg and 4kg which are separated  by a distance of 20 cm. And, we have to find the gravitational force between them.

Gravitational Force:

It is a force that acts between two bodies of some specific mass (Macro objects) that depends on the mass of the bodies and the separation between them.

Generally, The gravitational force between two objects of mass m₁ and m₂ separated at a distance of d is given by the formula:

$\rightarrow \sf \qquad F = \dfrac{Gm_1 m_2}{d^2}$

Substituting the values of m₁ and m₂ and d, we have

⇒      F = G(2 kg)(4 kg) / (20 cm)²

⇒      F = (6.67 × 10⁻¹¹ )(8) / 0.04

⇒      F = 13.34 * 10⁻¹¹ * 10²

⇒      F = 13.34 × 10⁻⁹ N
