If V=x^(2)y+y^(2)z then find vec(E) at (...

If `V=x^(2)y+y^(2)z` then find `vec(E)` at (x, y, z)

Text Solution

Verified by Experts

Given `V = (x^(2)y + y^(2)z)` and `vec(E) = -(del v)/(del r)`
`vec(E) = -[(del V)/(del x)hat(i) + (del V)/(del y) hat(j) + (del V)/(del z)hat(k)]`
`rArr vec(E) = -[2xy hat(i) + (x^(2) + 2yz)hat(j) + y^(2)hat(k)]`
