Question

Compare the strength of electrostatic force and gravitational force

Answer 1

at micro level

electrostatic force > gravitational force

at macro level

electrostatic force < gravitational force

Answer 2

Hey Dear,

◆ Electrostatic force -

Electrostatic force between two charged particles is given by -

F = k.q1.q2 / r^2

◆ Gravitational force -

Gravitational force between two masses is given by -

F = G.m1.m2 / r^2

◆ Comparison -

• Electrostatic force is a microscopic force while gravitational force is macroscopic force.
• Electrostatic force between any two particles is very much stronger than gravitational force between them.

Electrostatic force >>> Gravitational force

• This is because Coulomb's law constant is significantly larger than universal gravitational constant.

Hope this helped you.
