2. Electrostatic force can be quadrupled if the distancebetween two charges are _____________.
3. Electric field lines and electric potential lines are_______________ to each other.
4. The relationship between electric field and electricpotential is __________________.

Explanation / Answer

1.  the relationship of the electrostatic force ( F) and the E field ( E ) is F = Eq where q = charge of particle
2. Electrostatic force can be quadrupled if the distancebetween two charges are half we know force F 1 / r ^ 2              ( F ' / F ) = ( r / r ' ) ^ 2               (4F /F ) = ( r / r ' ) ^ 2                (r / r ' ) ^ 2 = 4                 r / r' = 2                      r ' = r / 2 3. Electric field lines and electric potential linesare perpendicular to each other.
4. The relationship between electric field and electricpotential is E = V / r or E = -grad v Or E = -dV / dr
