Volume 350m density 1.11kg m^3 find mass?

Mass is given by:

m = ρV

m = mass, ρ = density, V = volume

Given values:

ρ = 1.11kg/m³, V = 350m³

Plug in and solve for m:

m = 1.11(350)

m = 389kg

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.
