Question: Particles each with mass m and charge q accelerate through a potential difference of V = 100 volts and enter a region of uniform magnetic field B, where their paths are circular with radius R = 0.05m as shown in Fig. The magnitude of the field is B = 6.75 × 10-4 T.
a. Indicate the direction of B on a drawing.
b. Derive the following relationship between the radius R and q, m, V , and B:
R2 = m 2V q B2
c. Find the value of the charge-to-mass ratio (q/m) of these particles and identify them. Justify your answer!

The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically, it measures the fractional change in size per degree change in temperature at a constant pressure. Several types of coeffi..
A uniform plank of length 5 m and weight 231 N rests horizontally on two supports, with d = 1.43 m of the plank hanging over the right support. To what distance, x, can a person who weighs 446 N walk on the overhanging part of the plank before it ..
The only force on a 4.0-kg body as it moves along the x axis is given by F(subscript "x") = (14 - 6.1x) N, What is the maximum kinetic energy attained by the body
To focus a camera on objects at dissimilar distances, the converging lens is moved toward or away from the image sensor. A camera by a telephoto lens (f= 200.0 mm) is to be focused on an object first located at a distance of 3.5 m and then at 50.0 m...
