What: happens to the force between two objects, if
i) the mass of one object is doubled?
ii) the distance between the objects is doubled and tripled?
iii) the masses of both objects are doubled?
Answers
Answer:
- there creates a force called as friction
- please like me
Answer:-
(i) If the mass of object is doubled then the Gravitational force between them is also doubled.
(ii) If the distance between them is doubled then the Gravitational force between them decreased by 4 times.
And if the distance between them is tripled then the Gravitational force between them is decreased by 9times.
(iii) If the mass of both objects are doubled then the Gravitational force is increased by 4times.

Acceleration Due to Gravity:- The acceleration is caused due to the force of gravity is called acceleration due to gravity.
✧ Acceleration due to gravity is denoted by g .
✧ The acceleration due to gravity near the earth's surface is 9.8m/s².
To Calculate Acceleration due to gravity on any planets in the universe , we use
⟹ a = F/m = GM/R²
here
F is the force
a is the acceleration
m is the mass
G is the universal constant.
M is the mass of the body
R is the distance between them
The value of Universal Gravitational Constant is 6.67×10^-11 Nm²/Kg².
The value of Universal Gravitational Constant was discovered by Henry Cavendish.
✧ Universal Law Of Gravitation : The gravitational force of attraction between any two particle is directly proportional to the product of the masses of the particles and is inversely proportional to the square of the distance between the particles.
