What is the final velocity attained by the loop?

mgR/(B₀²a²)
mgR/(B₀a)
2mgR/(B₀²a²)
mgR/(2B₀²a²)

Correct answer: mgR/(B₀²a²)

Solution

The final velocity of the loop is determined by balancing the magnetic force and gravitational force. Using the given parameters, the velocity is proportional to mgR and inversely proportional to B₀²a².
