Hi lamy
we know ΔU=qΔV
solving for potential difference ΔV
we get ΔV=ΔU/q
ΔV= (Ub-Ua)/q
Ub is potential energy at b
Ua is potential energy at a
q is the charge of the particle
plug in and find out
Answer:
2315.8 m/s
Explanation:
For the charged particle to pass through this field undeflected, the electric force and the magnetic force acting on it must be equal
Electric force = Magnetic force
Electric force = Eq
Magnetic force = qvB
qvB = Eq
v = (E/B)
E = 440 N/C, B = 0.19 T
v = (440/0.19)
v = 2315.8 m/s
Mass=highest of neutron almost same of proton and mass of electrons is 1/1840 of protons the charge on neutron is neutral positive on Proton and negative on electrons Neutron and protons are inside the nucleus and keep the electron orbiting around them in different shells..
