1. A proton is moving along the positive x-axis with a speed of 1.50 × 105 m/s in a magnetic field of 2.00 T that is oriented along the positive y-axis. a. In the space below, sketch a diagram representing B and v

b. Find the direction and magnitude of the electromagnetic force on the proton.

c. What is the force when the proton moves along the y-axis?

2. Repeat item 1 for an electron.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
