Answer:
0.3 N
Explanation:
i = 400 A
B = 30 x 10^-6 T
L = 25 m
Force due the current carrying conductor placed in a magnetic field
F = B i L SinФ
where, Ф be the angle between length vector and magnetic field vector
F = 30 x 10^-6 x 400 x 25 = 0.3 N
<h2>
Velocity at maximum height is zero.</h2><h2>Acceleration at maximum height is 9.81 m/s² downward.</h2><h2>Acceleration when it just hits the ground is 9.81 m/s² downward.</h2>
Explanation:
For a ball thrown vertically upward, the velocity at maximum height is zero.
Acceleration is a constant for a ball thrown vertically upward, its is acceleration due to gravity.
Acceleration at maximum height is 9.81 m/s² downward.
Acceleration when it just hits the ground is 9.81 m/s² downward.
