Question

As charge q=1muC is placed at point (1m,2m,4m). Find the electric field at point P(0,-4m,3m)

Answer 1

Given:

Charge q =1muC

Coordinates of charge = (1m,2m,4m)

To find:

Electric field at point P(0,-4m,3m)

Answer:

• We know that, the electric feild at a point is given by E = kq / r²
• where k is a constant = 8.99 x 10^9 N m^2/C^2, q is the charge and r is the distance between the charge.
• E = 8.99 x 10^9 * 1 x 10^-3  / (1² + 6² + 1²)
• E = 0.2368 x 10^6

Electric field at point P(0,-4m,3m) = 0.2368 x 10^6 V/m
