Gravitational and Electric Fields

Question 1

Newtons law of universal gravitation

Answer 1

Every particle in the universe attracts every other particle with a force which is directly proportional to the product of the masses and inversely proportional to the square distance between their centers

Question 2

Weight

Answer 2

Gravitational force the earth exerts on any object on or near its surface

Question 3

Coulomb’s law

Answer 3

Force between two charges is directly proportional to the product of the charges and inversely proportional to the distance between the charges squared

Question 4

Magnitude of electric field

Answer 4

Force per unit positive charge

Question 5
