Point charges q1 and q2 are held in place at the (x,y) coordinates specified below. Point P is a point of interest, there is no charge at point P. Charge ?1 = +2.67 × 10 −9 ? at (1, 1) meters. Charge ?2 = −1.00 × 10 −9 ? at (5, 1) meters. Point P is at (5,00, 4.00) meters. Calculate the magnitude of the electric potential V at point P due to charges q1 and q2.
Point charges q1 and q2 are held in place at the
(x,y) coordinates specified below. Point P is a
point of interest, there is no charge at point P.
Charge ?1 = +2.67 × 10
−9 ? at (1, 1) meters.
Charge ?2 = −1.00 × 10
−9 ? at (5, 1) meters.
Point P is at (5,00, 4.00) meters.
Calculate the magnitude of the electric potential V at point P due to charges q1 and q2.
We are given 2 charges and there position. We are also given the point where potential is to be calculated.
We know that potential is given by
Where is the charge and distance of point where potential is to be calculated respectively.
We first find distance of the point given from each charge. We then find the potential due to each charge. Adding these potential gives the total potential at point.
