Two point charges in air are 2 m apart.One charge is three times the other charge.

Two point charges +3µC and –3µC are kept 20 cm apart in air. The electric field midway between the charges on the line joining them will be :42 × 105 N/C54 × 105 N/C63 × 105 N/C72 × 105 N/C

Two point charges in air are 2 m apart.If one charge is three times the other, their mutual force is 2.7 Into ten to the power five dyne What is the value of each charg

two-point charges placed at a distance 'r' in air exert a force 'F'. The distance at which they exert same force when placed in a certain medium (dielectric constant K) is :-

Two point charges are 10 cm apart and their combined charge is 9μC. Ifthey repel each other with a force of 18N, then calculate the magnitude ofeach charge

The sum of two point charges is 7μC. They repel each other with a force of 1N when kept 30cm apart in free space. Calculate the value of each charge.
