Calculate the electric field due to a charge of 35uc when it experiences an electrostatic force of 2×10^3N when placed in a vacuum.

Two point charges are located on the positive x-axis of a co-ordinate system. Charge is 2.0cm from the origin, another charge is 4.0cm from the origin. What is the total force exerted by these two charges on a charge located at the origin?

Find the total work done in moving a particle in a force field given by F = 2xyî + 3zĵ+ 5xk̂

along the curve x =t2

, y = 2t2+1, z = t3

-1 from t =2 to t=3?

Two charges lie on positive x-axis. Charge A (2.0 x 10-9 C) is 2.0 cm from the origin and Charge B is 4.0 cm from the origin. (-3.0 x 10-9 C). What is the total force exerted by these two charges on Charge C (5.0 x 10-9 C) located at the origin?     

three point charges, which are equally separated by a distance 20 cm, are arranged along the y-axis in a vacuum. The topmost charge bears a charge of – 4.0μC, the middle charge has a charge of +3.0 μC, and the bottom one carries a 7.0 μC charge. What is the magnitude and direction of the net electrostatic force that the middle charge experiences?

Four charges, q_{1} = 5.00 * 10 ^ - 7 * C q_{2} = - 3.00 * 10 ^ - 7 * C , q_{3} = - 2.00 * 10 ^ - 7 * C and q 4 =6.00* 10 ^ - 7 * t , are situated at the corners of a square if side 4.00 m. Find the potential at the center of the square.

Given: q_{1} = 5.00 * 10 ^ - 7 * c

q_{2} = - 3.00 * 10 ^ - 7 * C

q_{3} = - 2.00 * 10 ^ - 7 * C

q_{4} = 6.00 * 10 ^ - 7 * C
