The electric potential V at any point x,y,z (all in meters) in space is given by `V = 4x^2` V. The electric field at the point (1m, 0, 2m) is ……….. `Vm^(-1)`

Answer

8

Explanation

`E=-[(deltaV)/(deltax)hati+(deltaV)/(deltay)hatj+(deltaV)/(deltaz)hatk]rArrV=4x^(2)`
Therefore, `(deltaV)/(deltax)=8x and (deltaV)/(deltay)=0=(deltaV)/(deltaz)" "," "E=-8xhati" "or" "E" "at(1m,0,2m)" "is" "-8hatiV//m`
