Two point charges of 2.00 ?c and -2.00 ?c are 0.100 m apart. what is the electric field at the point midway between the two charges?

Answer :

Final answer:

The electric field at the point midway between two point charges can be calculated using the electrostatic formula. By substituting the given values, the electric field is approximately 2.88 x 10^4 N/C.

Explanation:

The electric field at the point midway between the two charges can be calculated using the formula:
E = k * (q1/r1^2 - q2/r2^2)

Where:
k is the electrostatic constant (9 x 10^9 N*m^2/C^2)
q1 and q2 are the magnitudes of the charges (2.00 µC and -2.00 µC)
r1 and r2 are the distances from the charges to the point midpoint

By substituting the given values (r1 = 0.05 m, r2 = 0.05 m), we can calculate the electric field to be 2.88 x 10^4 N/C.
