Acharge of +2.00 x 10^-9 c is placed at the origin, and another charge of +4.50 x 10^-9 c is placed at x = 1.6 m. the coulomb constant is 8.98755 x 10^9 n m2/c2. find the point (coordinate) between these two charges where a charge of +3.70 x 10^-9 c should be placed so that the net electric force on it is zero.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
