Question
Carefully study the following plot of electric field E in N/C versus distance r in m and answer the questions that follow. The electric field is directed radially outward, and the variation of E with r is independent of direction.
For each statement, select "True" or "False".
True False All points at a given distance 'd' from the origin are at the same electrostatic potential.
True False The above electric field could be that due to a negatively charged spherical shell.
True False The force on a charge placed at A has a tangential component.
True False The electric field is zero for r less than R.
True False The Electric field falls off as 1/r for r greater than R.
True False The work done by you to bring a point negative charge from infinity to A (it starts and finishes at rest) is positive.
