4.8 Comparing gravitational and electric fields

Question 1

Name some differences between gravitational and electrostatic forces

Answer 1

• Gravitational forces affect all particles with mass while electrostatic forces only affect particles with charge
• gravitational forces are always attractive while electrostatic forces can either be attractive or repulsive
• it is not possible to shield a mass from a gravitational field but it is possible to shield a charge from an electrostatic field
