Answer #1

Solution-

Mass of proton, m = 1.672*10^-27 Kg
mass of an electron, m' = 9.1*10^-31 Kg
Now the number of electrons would it take to the equal the mass of a proton can find out as ,   
                n = m / m'
                  = 0.1837 *10^4
                  = 1837

A neutron is an electrically neutral subatomic particle with a mass just slightly greater than that of a proton. A free neutron is radioactive and decays after a few minutes into other subatomic particles. In one experiment, a neutron at rest was observed to decay into a proton (mass 1.67××10−27−27 kgkg) and an electron (mass 9.11××10−31−31 kg). The proton and electron were shot out back-to-back. The proton speed was 5.0 ××1055 m/sm/s and the electron speed was 3.0 ××1077 m/sm/s....
