Question
Consider the following:
If a positively charged particle is accelerating through a region in which there is a uniform magnetic field, then the particle's velocity has to be perpendicular to the field.
(a) Is this statement valid?
(b) If you contend the statement is valid, how do you know?
(c) If you contend the statement is invalid, what is wrong with it?
(d) If the statement is invalid, restate it to give a valid statement.
(e) Is the valid statement (original, or you revision) a conditional or biconditional? How do you know?
(f) Would the following investigation be a legitimate test of the valid hypothesis (either the original or your revision), i.e., would the investigation provide data to either suuport or contradict the hypothesis? Explain.
Forty positively charged particles moving with an initial velocity perpendicular to a uniform magnetic field have their accelerations measured.
Explanation / Answer
here
The magnetic force exerted on the charged particle will be perpendicular to the particle’s velocity, and so also perpendicular to the direction of its motion. Since there is no component of the force in the direction of the particle’s motion, the work done by the magnetic force will be zero, and the kinetic energy of the particle will not change. The particle will change direction, but not change speed.
so when Forty positively charged particles moving with an initial velocity perpendicular to a uniform magnetic fieldthere will no change in the speed so the acceleration of particles will be zero
