Two 30 uc charges lie on the x-axis, one at the origin and the other at 9 m. a third point is located at 27 m. what is the potential at this third point relative to infinity? (the value of k is 9.0 x10^9 n-m^2/c^2.) a) 750 v b) 2500 v c) 2000 v d) 3000 v

25000 V

Explanation:

The formula for potential is

V = Kq/r

Potential at B due to the charge placed at origin O

V1 = K q / OB

V1 = 10000 V

Potential at B due to the charge placed at A

V2 = K q / AB

V2 = 15000 V

Total potential at B

V = V1 + V2 = 10000 + 15000 = 25000 V

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
