Question

What is the force between two small charged spheres having charges of 2 x 10-'C and 3 x 10-70
between them. What is the nature of this force?
6)
placed 0.3m apart in air.
7)
The force between two electrons when placed in air is equal to 0.5 times the weight of an electron.
Find the distance between two electrons. Given mass of electron = 9.1x10-1Kg.
Force between two charges is 36 x 10-N when separated by a certain distance. On increasing the
separation by 5 meter the force reduces to 25 x 10-6N. If one charge is 10 times the other, find the
initial separation and the magnitude of the charges.

9)
Two point charges q and 10g repel each other with a force of 3.6 x 10-5N. When they are separated
0.02m in vacuum. Find the charges. What will be the force if the charges are placed in a medium of
relative permittivity is 6?
10)
Two identical metal spheres are at a distance of 0.4m from each other. The charges on the spheres
are 9nC and -2nC. The spheres are brought in contact and then moved apart to the same distance.
Find the forces of their interaction before and after contact.
11)
Two identical insulated metal spheres charged with 10C on -50C are placed some distance apart.
They are made to touch each other and then separated by the same distance. Compare the forces
between them before after contact.
12)
Electric charges of 100uC and -100uc are placed at corners B and C of an equilateral triangle of
side 2m. Calculate the force exerted on a charge of 10uC placed at the corner A of the triangle.​
