1.THE ELECTRIC POTENTIAL V AT ANY POINT IS GIVEN BY V=4X2 then find electric field at (1m,0,2m )
1.THE ELECTRIC POTENTIAL V AT ANY POINT IS GIVEN BY V=4X2
then find electric field at (1m,0,2m )
Simply differentiate wrt x and put the given values.........
see buddy, E=-dV/dr, or as you say, partially differentiate it with respect to all coordinates in order to get the components of field... Hence E(x)=-dV/dx (it should be debra but its not on my keyboard so...) =-8x, and x=1, so E(x) =-8... Now, E(y)=0, as partially dofferentiating this expression with respect to y will give zero, similarily for the z one... Hence the final answer, E=8i

negative of diffrentiation is electric field
