Suppose we have a large number of identical particles, very small in size. Any two of them at 10 cm separation repel with a force of 3 x 10^-10N.find the value of charge

Suppose we have a large number of identical particles, very small in size. Any two of them at 10 cm separation repel with a force of 3 x 10^-10N. If one of them is at 10 cm from a group of n others, how strongly do you expet it to be repelled?

Suppose we have a large number of identical particles, very small in size. Any two of them at 10 cm separation repel with a force of 3 x 10^-10N. Suppose you measure the repulsion and find it 6xx10^-6N . How many particles were there in the group?

Two equal charges placed in air and separated by a distance of 2 m repel each other with a force of 10^-4 N. Calculate the magnitude of either of the charges.

The distance between two equal balls having unlike charges is 2cm. The radii of the balls are much less than the distance between them. The balls attract each other with a force of 36xx10^(-5) N. After the ball have been connected by a wire and latter has been removed, the balls repel each other with a force of 20. 25xx10^(-5)N. Determine the original charges on the balls

Two electrons have bene removed from each atom. Find the distance between two such atoms, if they repel each other with a fore of 8.8 xx 10^-9N , when placed in free space.

Calculate the Coulomb.s force between two alpha particles separated by a distance of 3.2xx10^-15m

If P is the number of natural number whose logarithms to the base 10 have the characteristic p and Q is the number of natural numbers logarithms of whose reciprocals to the base 10 have the characteristic -q, then find the value of log_(10)P-log_(10) Q .
