Why is si system better than CGS system

SI unit is same everywhere however in cgs unit there are different units of measurement

SI unit is adopted internationally and the units are fixed and do not change at any place

hope that helps !

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

its c its is a mixture of gases
