Question

The distance between two charges \( q_1 = +2 \,\mu\text{C} \) and \( q_2 = +8 \,\mu\text{C} \) is \( 15 \text{ cm} \). Calculate the distance from the charge \( q_1 \) to the points on the line segment joining the two charges where the electric field is zero.

• A. $1 \text{ cm}$
• B. $2 \text{ cm}$
• C. $3 \text{ cm}$
• D. $4 \text{ cm}$
• E. $5 \text{ cm}$

Hint:

For two like charges, the neutral point always lies between them[ 14]. For unlike charges, it lies outside the segment, closer to the charge with the smaller magnitude.
