A uniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance 5.4 cm. A proton is released from rest at the surface of the positively charged plate. The value of the constant electric field between the plates is 166.8 N/C.

Use:

Mass of a proton= 1.67 × 10-27 kilograms

Charge of a proton = 1.60 × 10-19 C

k = 9 x 109 Nm2 / C2

ε0 = 8.85×10−12 F⋅m−1

1. Calculate the value of the acceleration of the proton then enter the letter corresponding to the correct answer in the box (this entry requires exact match. please enter the letter in lower case and do not enter any spaces, commas or dotts).

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.
