Two point charges, q1 = +25 nC and q2 = -75 nC, are separated by a distance r = 3.0 cm. Find the magnitude and direction of the electric force (a) that q1 exerts on q2 and (b) that q2 exerts on q1.

Step 1
The formula is: F = k * |q1 * q2| / r^2 where k is Coulomb's constant (8.99 * 10^9 N m^2/C^2), q1 and q2 are the charges, and r is the distance between them. Substituting the given values: F = (8.99 * 10^9 N m^2/C^2) * (25 * 10^-9 C) * (75 * 10^-9 C) / (0.03 Show more…

a. There are two charges q1 = 35 μC and q2 = 50 μC placed 0.5 m apart and fixed in place. A third charge, q3 = 15 μC, is placed directly between the charges. What is the magnitude of the force on q3? b. Two charges are placed on the x-axis 3 m apart from each other. Q1 is on the left and has a charge of 30 nC and Q2 is on the right and has a charge of -220 nC. What is the magnitude of the electric field 1.5 to the right of Q2? Answer both please

Two point charges are located on the $y$ -axis as follows: charge $q_{1}=-1.50 \mathrm{nC}$ at $y=-0.600 \mathrm{m},$ and charge $q_{2}=+3.20 \mathrm{nC}$ at the origin $(y=0) .$ What is the total force (magnitude and direction) exerted by these two charges on a third charge $q_{3}=+5.00 \mathrm{nC}$ located at $y=-0.400 \mathrm{m} ?$
