Answer :
The magnitude of magnetic field is 2194 N/C
Given,
r = 4 m
Q = 3.9 µC
Q = 3.9 × 10⁻⁶ C
Let, the electric field is " E "
E = (k × Q/r²)
E = (9×10⁹×3.9×10⁻⁶/4²)
E = 2193.75 N/C
E = 2194 N/C
A magnetic discipline is a vector field that describes the magnetic affect on moving electric prices, electric powered currents, and magnetic substances. A shifting charge in a magnetic subject reviews a pressure perpendicular to its personal velocity and to the magnetic area.
