In a diagram, how do we represent areas in which the electric field is stronger?By drawing the field lines closer togetherBy using different colours for different field linesBy making the field lines thickerBy adding labels to different areas of the diagram2A small positive charge is placed into an electric field.  In which direction will it experience an electric force?At right angles to the field linesOpposite to the direction in which the field lines are pointingIn the same direction in which the field lines are pointingDirectly towards a negative charge3A small negative charge is placed into an electric field.  In which direction will it experience an electric force?Opposite to the direction in which the field lines are pointingIn the same direction in which the field lines are pointingAt right angles to the field linesDirectly towards a negative charge4What is meant by an electric field?A region in which a charged particle will experience a forceAn area of land which is being used for the generation of electricityA large collection electrical chargesA board which can be used for the building of an electric circuit

A positive charge placed in an electric field will experience a forceIn the opposite direction of electric fieldIn the same direction as that of electric fieldDepends on the situationCan’t say

A negative point charge is in an electric field created by a positive point charge.Part AWhich of the following is true?The field points away from the positive charge, and the force on the negative charge is in the opposite direction to the field.The field points away from the positive charge, and the force on the negative charge is in the same direction as the field.The field points toward the positive charge, and the force on the negative charge is in the same direction as the field.The field points toward the positive charge, and the force on the negative charge is in the opposite direction to the field.

The diagram shows the cross sections of equipotential surfaces at various distance 𝑥 from apoint 𝑂 in an electric field.(a) Explain whether the electric field is uniform.(b) Find the magnitude of the electric field strength.(c) What is the direction of the electric field?(d) What is the force acting on an electron in the electric field?

A positive charge is placed in an electric field that points south. What direction is the force on the positive particle?

Electric field lines from positive charges point radially , and point radially for negative charges.
