Particle 1 and particle 2 have masses of m1 = 2.2 × 10-8 kg and m2 = 4.8 × 10-8 kg, but they carry the same charge q. the two particles accelerate from rest through the same electric potential difference v and enter the same magnetic field, which has a magnitude b. the particles travel perpendicular to the magnetic field on circular paths. the radius of the circular path for particle 1 is r1 = 8 cm. what is the radius (in cm) of the circular path for particle 2?

Explanation:

Given

same charge on both masses

potential Energy due to Magnetic Field =Kinetic Energy of Particle

and we know

Force due to magnetic field will Provide centripetal Force

and B is equal for both particles

thus

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
