Question 1
In which of the directions should a dipole be aligned with respect to a uniform external electric field, such that it has minimum potential energy?
Question 2
Three capacitors each of capacitance C and of breakdown voltage V are joined in series. The capacitance and breakdown voltage of the combination will be
Question 3
The electric potential at a point (x, y, z) is given by V = -x2y - xz3 +4
The electric field
at that point is
The electric field
at that point is Question 4
A parallel-plate capacitor of area A, plate separation d and capacitance C is filled with four dielectric materials having dielectric constants k1, k2, k3 and k4 as shown in the figure below. If a single dielectric material is to be used to have the same capacitance C in this capacitor, then its dielectric constant k is given by
Question 5
If V = ar where a is a constant and r is the distance, then electric field at a point will be proportional to
