Question
The electric potential V as a function of distance x (in metre) is given by V = (5x2 + 10x − 9) volt. The value of electric field at x = 1 m would be :
Options
A.- 20 volt/m
B.6 volt/m
C.11 volt/m
D.-23 volt/m
Solution
E = − 
= − 10 x − 10
∴ E(x =1m) − 10 (1) − 10 = − 20 V/m
= − 10 x − 10∴ E(x =1m) − 10 (1) − 10 = − 20 V/m
