An electron follows a helical path in a uniform magnetic field of magnitude 0.340 t. the pitch of the path is 6.00 µm, and the magnitude of the magnetic force on the electron is 1.85 10-15n. what is the electron's speed?

The electron's speed is 34007.35 m/s

Explanation:

It is given that,

Magnetic field, B = 0.34 T

Magnetic force on the electron,

The electron follows a helical path. We have to find the speed of an electron. The formula for magnetic force is given by :

q = charge on an electron,

v = velocity of an electron

v = 34007.35 m/s

Hence, this is the required solution.

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.
