Question

Two large plane sheets P₁ and P₂ having charge densities + σ and – 3 σ respectively are arranged parallel to each other as shown in the figure. Find the net electric field (E) at points A, B and C.

Two point charges of 3 μC and 4 μC are kept in air at (0.3 m, 0) and (0, 0.3 m) in x-y plane. Find the magnitude and direction of the net electric field produced at the origin (0, 0).

A uniform electric field of magnitude 500 N C⁻¹ points along the +x direction. A small point charge of +2 μC is placed at the origin. The force experienced by the charge is:

Consider three charges q1, q2, q3 each equal to q at the vertices of an equilateral triangle of side l. What is the force on a charge Q (with the same sign as q) placed at the centroid of the triangle, as shown in Fig. 1.6?
