as we know that the velocity vectors are at right angles
magnitude = ?
hypotenuse of a right
triangle.
v^2 = 90^2 + 4^2
v^2 = 8116
Taking the square root of both sides here we get,
v = 90.1 m/s
hope it helps

Answer:
Magnetic flux will be equal to
Explanation:
It is given radius of circular loop r = 0.10 m
Area of circular loop
Magnetic field B = 0.20 T
Angle between plane of loop and magnetic field
Magnetic flux will be equal to
So magnetic flux will be equal to
