Potential energy = (mass) x (gravity) x (height)
Divide each side by (G x H) : Mass = PE / (G x H)
PE = 6 joules
Gravity = 9.8 m/s
Height = 3 m
Mass = 6 / (9.8 x 3) =
6 / (29.4) = <em>0.204 kg</em>
(weighs about 2 newtons or 7.2 ounces on Earth)
Answer:
F = 29.484 N
Explanation:
The force on the rod can containing the current placed in external magnetic field is:
F = BIL
where,
B = magnitude of the field
I = current in the loop
L = length
then,
F = 7.80 * 18.0 * 0.21
F = 29.484 N
