The bar shown in the figure below moves on rails to the right
with a velocity , and a uniform, constant magnetic field is
directed out of the page. Which of the following statements are
correct? (Select all that apply.)
a.The induced current in the loop is zero.
b.The induced current in the loop is clockwise.
c.The induced current in the loop is counterclockwise.
d.An external force is required to keep the bar moving at constant
speed.
e.No force is required to keep the bar moving at constant
speed.
The correct statements are following
b. the induced current in the loop is clockwise
$$ \text { Since } F=q(V \times B) $$
d. An external force is required to keep the bar moving at constant speed
