A positive charge, q1, of 5 µC is 3 × 10–2 m west of a positive charge, q2, of 2 µC. What is the magnitude and direction of the electrical force, Fe, applied by q1 on q2?

Charges of +2 µC and +3 µC are 4 mm from each other. Raina’s group draws four diagrams trying to represent the electrical force between the charges.Which diagram is correct?

What is the direction of the electric field at a point directly to the left of a positive charge, Q?

The current in the circuit shown is 2.0 A.

Electric field lines can never cross. What would crossed electric field lines indicate?
