What is mechanical energy?

it is the energy found in electrons

it is the energy of motion

it is all stored energy

it is the sum of the kinetic and potential energies of an object

It is the sum of the kinetic and potential energies of an object

Hope this is helpful :)

i believe your answer is d mgf2

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.
