Question

Two point charge 0.01u and —0.01u are placed 10cm apart in vacuum , calculate the magnitude of electric field intercity at the middle point of the line joining the charge and mention it's direction ​

Answer 1

E=E1+ E2

E=K×0.01×10^-6. k×0.01×10^-6

------------------. +. ------------------

(5×10^-2)^2. (5×10^-2)^2

E=2k×1×19^-8

--------------

25×10^-4

200

--------. ×10^6 K

25

E=8×10^-6×9×10^9

E=7.2×10^4 N/C
