Figure shows the electric lines of force emerging from a charged body. If the electric field at`A` and `B` are `E_(A)` and `E_(B)` respectively and if the displacement between `A` and `B` is `r` then

The figure shows the electric lines of force emerging from a charged body. If the electric fields at A and E_(A) and E_(B) respectively and if the the distance between A anf B is r, then

Some electric lines of force are shown in figure. For points a and B

The figure shows electric field lines. If E_(A) and E_(B) are electric fields at A and B and distance AB is r, then

Figures shows an electric line of force which curves along a circular arc.The magnitude of electric field intensities is same at all points on this curve and is equal to E .If the potential at A is V ,the potential at B is

Write the dimensions of E/B . Here, E is the electric field and B the magnetic field.

Figure shows the electric field lines around three point charges A, B and C . Which of the following charges are positive?

Figure shows the field lines of apoint negative charge. In going from B to A, the kinetic energy of a small negatice charge will
