Question

According to the equation r = (mv)/(Be), faster moving particles
Options
A move in a smaller circle
B move straight
C move in a bigger circle
Correct Answer
D move randomly
Correct Answer

Option C is the correct answer.

Detailed Explanation

Since radius r is directly proportional to velocity v in this formula, a faster particle traces a larger circular path.

Hint

Look at how r depends on v in the formula — is it direct or inverse proportionality?
