WebNov 29, 2014 · Find the electric field caused by a disk of radius R with a uniform positive surface charge density σ σ and total charge Q, at a point P. Point P lies a distance x away from the centre of the disk, on the axis through the centre of the disk. σ = Q πR2 σ = Q π R 2. To find dQ, we will need dA d A. Note that dA = 2πrdr d A = 2 π r d r. WebThe electric potential V of a point charge is given by. V = k q r ( point charge) 7.8. where k is a constant equal to 8.99 × 10 9 N · m 2 /C 2. The potential at infinity is chosen to be zero. Thus, V for a point charge decreases with distance, whereas E → for a point charge …
