Gravity is directly proportional to the product of the two. Masses and inversely proportional to the square distance between the two masses.
Answer:
D) follows a circular path
Explanation:
This is because the magnetic force F on the charge, q due to the magnetic field B with velocity vector v perpendicular to it, equals the centripetal force acting on the charge.
So, F = Bqv = mv²/r.
So it follows a circular path.
From the calculation and the momentum of the body, the velocity is 62 m/s
<h3>What is momentum?</h3>
The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.
Hence;
7440 kg-m/s = 120 kg * v
v= 7440 kg-m/s/120 kg
v = 62 m/s
