What magnitude electric field is needed to make it hover

Reference no: EM131002877

The mass-to-charge ratio (m/Q) of a proton is 1.044 x10^-8 kg/C. You want to build a particle trap in a lab. What magnitude electric field is needed to make it hover in a vacuum, i.e., not fall under the influence of gravity?
