Gravitational and Electric Fields Concepts

What does the magnitude of the electric field depend on?

• The speed of the charge

• The charge and distance from the center of charge

• The mass and distance from the center of mass

• The gravitational constant and mass

How does the gravitational field around Earth compare to the electric field around a negative charge?

• They are completely different in appearance

• They look identical due to similar governing equations

• The gravitational field is horizontal while the electric field is vertical

• The electric field is stronger than the gravitational field

What is the formula for the magnitude of the gravitational field?

• Big G * M / r^2

• K * Q / R^2

• Electrostatic force divided by mass

• Force of gravity divided by charge

What is the direction of the gravitational field on Earth's surface?

• Horizontal and constant

• Vertical and directed upward

• Vertical and directed downward

• Random and variable

How is the gravitational field on Earth's surface similar to the electric field between parallel plates?

• Both are horizontal and constant

• Both are nearly constant and directed vertically

• Both are random and variable

• Both depend on the speed of the object
