Is acceleration due to gravity the same for all objects? explain.

Mass doesn't affect acceleration due to gravity in any measurable way. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.

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.
