Question

A positive charge that is free to move but is at rest in an electric field E experiences a force that is
a) In the same direction as E. c) Perpendicular to E.
b) In the direction opposite to E. d) Zero because the speed is zero.

Answer 1

Perpendicular to E...

Answer 2

Answer:

The correct answer is option (a)

(a) In the same direction as E (electric field)

Explanation:

• If the positive charge is at rest in a electric field E, the path of the positive charge will be tangential to the line of force.
• The tangent will coincide with the electric field line, when the electric field lines are in straight line so the positive charge will move along the direction of the electric field.
• It is due to the electrostatic force acting on it.
• When a positive charge is placed in a electric field it will move in the direction of the electric field where the negative charge will move in the direction of electric field.
• The angle between the displacement and field vector or the angle between the force and displacement vector is given as θ.

Answer: A positive charge that is free to move but is at rest in an electric field E experience a force that is n the same direction as E

Option (a)
