Show The Factor by Which Electricity is Stronger than Gravity

The video explains that the electric force is significantly stronger than the gravitational force, using protons and electrons as examples. It approximates the ratio of these forces and explains why this concept is unintuitive, highlighting the role of charge and mass. The video also discusses why we don't experience large electric forces in daily life due to charge cancellation, unlike gravity, which is always felt due to mass.

What is a common misconception about the strength of electric and gravitational forces?

• Both forces are equal in strength.

• Electric force is weaker than gravitational force.

• Electric force is stronger than gravitational force.

• Gravitational force does not exist.

Which two particles are used to approximate the ratio of electric to gravitational force?

• Proton and electron

• Photon and electron

• Electron and neutron

• Neutron and proton

What is the approximate charge of an electron used in the calculation?

• 1.602 * 10^-19 coulombs

• 10^-30 kilograms

• 9 * 10^9 coulombs

• 10 * 10^9 coulombs

What is the calculated ratio of electric force to gravitational force for two fundamental particles?

• 10^19

• 10^9

• 10^30

• 10^40

Why don't we feel the electric force from the Earth?

• The charges in the Earth cancel each other out.

• Mass can be hidden, unlike charge.

• The Earth has no electric charge.

• Electric force is weaker than gravitational force.

What is a reason for the rarity of encountering large amounts of charge in everyday life?

• Charges are always balanced.

• Mass is more common than charge.

• Large charges are only found in lightning.
