I don't know how to do this trouble, I need help with Problems A,B, C, and D. Can you label which one is A,B,C and D

Problem 2: A proton orbits a long charged wire, making N = 1.0 x 106 revolutions
per second. The radius of the orbit is R = 1.0 cm (see Fig.2). What is the wire's linear
charge density?
a) For such motion to be possible, should the charge on the wire be positive or
negative? In Fig.2, draw the electric field created by the wire.
b) Express the centripetal acceleration of the proton in terms of its orbital pa-
rameters R and N.

c) Express the acceleration of the proton in terms of the electric field acting on it. You need to use the
formula for the field of an infinite charged wire.

d) Equating the two expressions for the proton's acceleration, deduce the absolute value of the linear
charge density on the wire, [2].

Expert Solution
Step 1

The charge per unit length is referred to as linear charge density. At every point on a line charge distribution, the linear charge density is the amount of  charge per unit length, expressed in coulombs per meter. Electric charge can be positive or negative , hence charge density can also be positive or negative.

Centripetal acceleration is a characteristic of an object's motion in a circular route. Centripetal acceleration applies to any item travelling in a circle with an acceleration vector pointing in the direction  of the circle's center. 

E.M. radiation is produced when a proton is propelled by an electric field, hence it should lose mass.
