Electric field lines due to negative point charge is always radially towards it.

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 $\text{'}\mathrm{P}\text{'}$.

Write the properties of electric lines of forces.

Write the properties of electric lines of force.

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

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)
