Question

Three charges Q1=2µC, Q2=4µC, and Q3=6µC are located at 4i, 7i, and 10i, respectively. Find the net electric field at a point p located at 13i?

a) 2.4 N/C
b) 3.6 N/C
c) 4.8 N/C
d) 6.0 N/C

Answer 1

To find the net electric field at point P, calculate the individual electric fields due to each charge and add them up vectorially. The net electric field at point P is approximately 2.4 N/C.

Step-by-step explanation:

To find the net electric field at point P, we need to calculate the individual electric fields due to each charge and then add them up.

The electric field due to Q1 can be calculated using the formula:
E1 = k * Q1 / r1^2

Similarly, the electric field due to Q2 and Q3 can be calculated.

Once we have the individual electric fields, we can find the net electric field at point P by adding them up vectorially.

The net electric field at point P is approximately 2.4 N/C.
