Figure shows electric field lines. If $E_A$ and $E_B$ are electric fields at $A$ and $B$, then

Write the properties of electric lines of forces.

The electric field lines of a positive charge is as shown in figure:

Give the sign of work done by the field in moving a small positive charge from $\text{'}\mathrm{Q}\text{'}$ to $\text{'}\mathrm{P}\text{'}$.

The electric field lines on the left have twice the separation on those on the right as shown in figure. If the magnitude of the field at $A$ is $40 {\mathrm{Vm}}^{-1}$, what is  the force on $20 \mu \mathrm{C}$ charge kept at

Write the properties of electric lines of force.

Figure shows three arrangements of electric field lines. In each arrangement, a proton is released from rest at point A and then accelerated through point B by the electric field. Points A and B have equal separations in the three arrangements. If $p_1,p_2$ and $p_3$ are linear momentum of the proton at point B in the three arrangement respectively, then

A small point mass carrying some positive charge on it, is released from the edge of a table. There is a uniform electric field in this region in the horizontal direction. Which of the following options then correctly describe the trajectory of the mass ? (Curves are drawn schematically and are not to scale)
