Question
Four point charges equal in magnitude are arranged at the corners of a square as shown in the figure
I know the answer is D, C, C, but can you explain and show me the drawing please, thank you!
Four point charges equal in magnitude are arranged at the corners of a square as showm in the figure. 2 pt What is the direction of the electric field at point a 5. AO To the left. BO To the right. CO Up (to the top of the page). DO The electric field is zero at this point. EO Down (to the bottom of the page). pt What is the direction of the electric field at point b? 6. AO The electric field is zero at this point. BO Up (to the top of the page). CO To the right. DO To the left. EO Down (to the bottom of the page). 2 pt Select the only true statement about the electric po- ential at points a, b and c. 7. AO The electric potential equals zero at points a and c but not at b. BO The electric potential equals zero at points a and b but not at c. CO The electric potential equals zero at points a, b and c. DO The electric potential equals zero at point a but not at b or c. EO The electric potential equals zero at none of these points.Explanation / Answer
here,
as the charges at the corner are equal
5)
the electric feild due the diagonal charges will cancel out
so the net electric feild at the centre is zero
the electric feild at the centre
D) the electric feild is zero at this point
6)
at point b
the vertcial component of elctric due to bottom charges cancels out
and the electric feild is towards -ve charge
so, the net electric feild is towards right (C)
7)
the electric potential , V = k* q/r
as the magnitude of charges are equal
and the distance of points from +ve charge equal to the disance from the negative charges
the potential is zero at a , b and c (C)
