The electric field in a region of space varies as E = (3v//m)xhat(i)+(4v//m)yhat(j)+(5v//m)zhat(k) Consider a differential cube whose one vertex is (x, y, z) and the three sides are dx, dy, dz, sides being parallel to the three coordinate axes.

Answer»

The flux of electric field through the differential cube is zero
The flux of electric field through the cube = 12 dx dy dz
The CHARGE enclosed by the cube is zero.
The charge enclosed by a spherical SURFACE of radius r, centered at ORIGIN is `16 PI epsilon_(0)r^(3)`
