Both forces may be either attractive or repulsive.The gravitational force must be attractive, whereas the electrostatic force may be either attractive or repulsive.

The gravitational force may be either attractive or repulsive, whereas the electrostatic force must be attractive.

The energy required to move a charge of 8.00 × 10−19 coulomb from point A to point B is ġ4 Which statement describes the gravitational force and the electrostatic force between two charged particles?

Which arrow represents the direction of the net force acting on the electron when the electron is at position A? ġ3 The potential difference between two points, A and B, in an electric field is 2.00 volts. What is the speed of cart A after the spring is released? ġ2 An electron in a magnetic field travels at constant speed in the circular path represented in the diagram below. After the spring is released, the speed of cart B is 6.0 meters per second, as represented in the diagram below. When a compressed spring attached to one of the carts is released, the carts are pushed apart. What is the magnitude of the electric field strength at the location of the electron? ġ1 A 7.0-kilogram cart, A, and a 3.0-kilogram cart, B, are initially held together at rest on a horizontal, frictionless surface. What is the angle of reflection? ġ0 An electric field exerts an electrostatic force of magnitude 1.5 × 10−14 newton on an electron within the field.
