It is <u>true </u>that an equipotential surface is a three-dimensional surface on which the electric potential is the same at every point.
Assuming that that this is a true/false question.
Also, e<span>lectric field lines and equipotential surfaces are always mutually perpendicular, for some extra information. </span>
As seagull drops a shell from rest at a height of 12 m, so we use kinematic equation of motion,
Here, h is the height, u is initial velocity , v is final velocity and g is acceleration due to gravity.
Given, h = 12 m.
We take, and because seagull drops a shell from rest.
Therefore, the speed of shell when it hits the rocks,
