Strength of electric field that will levitate aproton

Reference no: EM13560492

Protons carry an electric charge ofe = 1.60×10−19 C, electronscarry a charge of −e, and neutrons are electricallyneutral. Protons and neutrons have a mass of1.67×10−27 kg, and electrons have a mass of9.11×10−31 kg. A uniform electric field can exerta force on a charged particle that effectively neutralizes the force of gravity on the particle, causing it to be "weightless."What is the strength of the electric field that will levitate (a) aproton? (b) an electron? (c) an alpha particle (two protons and two neutrons)?
