Coulomb. It is due to arise the name of the scientist.

What is the value of charge of electron?

-1.6×10-19 C

Write the formula of coulomb law.

1/4πԐ0 q1 q2/r2

Write the value of the constant k in coulomb law.

9×109 Nm2C2

What is the SI unit of electric field?

NC-1 (Newton per Coulomb)

"The electric field lines never intersect". This statement is correct or wrong. Explained.

Yes electric field lines are never intersecting. If two lines cross at a       point, then there will be two different electric field vectors at the same   point. This is physically impossible.

Calculate the force experienced by the two charges for the following cases:

q= + 2 μ C      q2 = -3 µC  distance = 1m

1/4πԐ0 q1 q2/r2

9×109× (2×10-6) × (-3×10-6)/12

= - 54×10-3 N

If the net charge is zero in the object, what it is said to be?__________

It said to be electrically neutral.
