Question

.4
Two point charge qp=+2uC and qq =-2uC are placed at a
distance of 10 cm in air/vacuum.
(a) Calculate the electric field intensity along the center of line
joining the two chages.
(b) If a test charge qr= -1.2x10-°C is placed at center of the
PQ write the value of force acting on test charge ar and
its direction.​

Answer 1

two point charge qp=+2ohm c and qq=-2ohmc are placed at a distance of 10cm in air/vacuum.

a calculate the electric field intensity along the center of line joining the two charges
