expression for the net force per unit length due to the currents 1 and 2 on current 3. Use unit vector notation expression for the net force per unit length due to the currents 1 and 2 on current 3. Use unit vector notation 3. A positively charged particle of charge q and mass m is accelerated in a uniform electric field from rest to a speed v in the horizontal direction. Thereafter, it enters a magnetic field region, with the uniform magnetic field, B, pointing perpendicularly to the velocity, out of the page. (a) If the voltage applied to accelerate the particle is V, derive an expression for the particle's mass in terms of q, B, V and the particle's cyclotron radius. (b) For two singly ionized Boron isotopes with the atomic mass numbers 10 and 11, respectively, what would be the distance on a photographic plate between the marks these particles leave once they completed one half of their circular track? Assume that 1-60mT. V = 1 kV
