1.	A disk of radius a/4 having a uniformly distributed charge 6C is placed in the x-y plane with its centre at (−a/2,0, 0). A rod of length a carrying a uniformly distributed charge 8C is placed on the x-axis from x =a/4 to x = 5a/4. Two point charges −7C and 3C are placed at (a/4, −a/4,0) and (−3a/4, 3a/4, 0), respectively. Consider a cubical surface formed by six surfaces x =?
