Two Point Charges Two point charges, 4.2x10^(-9) C and -4.0q, are fixed in place 50 cm apart. Find the point along the straight line passing through the two charges at which the electric field is zero.
Added by Dana C.
Step 1
We have two point charges: $q_1 = 2.1 \times 10^{-4} C$ and $q_2 = 4.0q_1 = 8.4 \times 10^{-4} C$. Show more…

Charge q1= 20.0 nC is placed 41.0 cm from charge q2, in the positive direction. If q2 has a charge of -31.0 nC and is at the origin. Find the point (in cm) along the straight line passing through the two charges ag which the electric field is zero.

A 5.0-μC point charge is placed at the 0.00 cm mark of a meter stick and a -4.0-μC point charge is placed at the 50 cm mark. At what point on a line joining the two charges is the electric field due to these charges equal to zero?

2) A Q1 = +5.0 nC point charge and a Q1 = - 6.0 nC point charge are 4.0 cm apart on the x-axis. Find the point on the x -axis where the electric field is zero. Hint: Draw Electric vectors for both charges at a point between the two charge, and also at a point outside of the two charges on the right side of Q2 and on the left side of Q1
