A $72 \mathrm{nC}$ charge is located at $\mathrm{x}=3.00 \mathrm{~m}$ on the $\mathrm{x}$-axis and an $8.0 \mathrm{nC}$ charge is located at $\mathrm{x}=7.0 \mathrm{~m}$. At what point on the $\mathrm{x}$-axis is the electric field zero?

Question

Quizplus · Accepted Answer

The electric field is zero at a point where the fields due to both charges cancel each other out. This occurs closer to the smaller charge. Calculating the point using the formula for electric field and setting them equal gives approximately $6.0 \mathrm{~m}$.
