You have arranged that the magnetic field in a particular region of space is due north with a value of 0.0050 t. an electron enters the field traveling to the west with a speed of 5.5 percent of the speed of light. as a result, the electron experiences a magnetic force which is upwards

. (a) what is the strength of this magnetic force? give your answer in femtonewtons. (note: the prefix "femto" represents 10^(- fn

(b) what is the amount of the resulting acceleration of the electron? get the mass of an electron from the inside back cover of your textbook. give your answer in pm/s2 (note: the prefix "p" is for "peta", which represents 10^( pm/s2

(c) what will be the result of the acceleration that you have calculated in part (b)?

a.)the speed of the moving electron will change but its direction of motion will remain constant..

b.)both the speed and direction of the moving electron will change.

c.) the direction of the moving electron will change but its speed will remain constant.

Explanation:

Magnetic field B = 5 x 10⁻³ T

Speed of electron

= ( 5.5 /100) x 3 x 10⁸

= 165 x 10⁵ m /s

Magnetic force on electron

F = Bqv

B is magnetic field , q is charge on electron and v is its velocity

= 5 x 10⁻³ x1.6 x 10⁻¹⁹ x 165 x 10⁵

1320 x 10⁻¹⁷ N

13.2 X 10⁻¹⁵ N

= 13.2  f N

b )

Acceleration = force / mass of electron

= 1320 x 10⁻¹⁷ / 9.1 x 10⁻³¹

= 14.5 x 10¹⁵ m/s²

= 14.5 Pm/s²

c ) The direction of the moving electron will change but its speed will remain constant.

This is so because the magnetic  force will be acting perpendicular to the velocity of electron all the time in course of its motion.

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.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
