Question

Two point charges 0.01 microcolomb and -0.01 are placed 10 cm apart in vacuum . Calculate the magnitude of electric field intensity at the middle point of the line joining the charges and mention its direction class 12 physics

Answer 1

Q₁=10⁻⁸ C

Q₂= -10⁻⁸ C

E at midpoint

E = k Q₁/r² + kQ₂/r²

E = k [2 X 10⁻⁸/ 25 X 10⁻²]

E = 72 X 10⁻⁸ N/C towards -0.01 C

Answer 2

Answer:

7.2×10⁴N/C

Explanation:

Complete and correct solution is given in the attachments...

As it is asking about the electric field intensity at the meat point and given two charges both of them are applying electric field at the same point simultaneously so we need to calculate them by adding both the electric field intensity given by both charges....
