What is the direction and speed of the proton

Reference no: EM13551168

A neutron decays into a proton, and an electron. The neutron was initially at rest. After the decay, the electron is found to be travelling at a velocity of 0.2 c in the positive x direction (here, the speed is represented as a fraction of the speed of light,
