in which situation would an object weigh the least? (assume all the objects have the same mass)
an object on earth
an object on the moon
an object half-way between the earth and moon
an object in space closer to the moon than the earth

an object on the moon.

explanation:

just like it the water. you don't have to carry weight. so on the moon, you're floating so you don't have weight to carry.

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.
