The electric potential existing in space is
V(x, y, z) = A (xy + yz + zx).
(a) Write the dimensional formula of A.
(b) Find the expression for the electric field.
(c) If A is 10 SI units, find the magnitude of the electric filed at (1m, 1m, 1m).
Given:
Electric Potential :V(x,y,z) = A (xy + yz + zx).
A = 10 SI units.
Formula used:
(a)
From the given data V(x,y,z) = A (xy + yz + zx), we can say that Voltage is the product of A and length2(xy+yz+zx)
Volt = A× m2We know that Volt =
, where Q=
Thus, dimensions of A are
(b)
Formula for electric field is:Where
Hence , expression of electric field is
(c)
A = 10 SI units
(x,y,z) = (1m,1m,1m)
Substituting in the expression of E we get:Magnitude of Electric field is
Hence, magnitude of Electric field at (1m,1m,1m0 is 34.64 NC-1.
