Force Acting on Current Carrying Conductor: Practice Problem & Solution

A positively charged particle moving due East enters a region of uniform magnetic field directed vertically upwards. This particle will (1997)
Move in a circular path with a decreased speed
Move in a circular path with a uniform speed
Get deflected in vertically upward direction
Move in circular path with an increased speed

Solution Explained:

To solve this problem, we apply the core principles of Force Acting on Current Carrying Conductor. Understanding the underlying formula is key to arriving at the correct answer below:

Magnetic force is always perpendicular to velocity, doing no work on the particle. Consequently, the speed remains constant while the particle moves in a circular path.
