To solve this problem it is necessary to apply the agreements related to Strength and Work.
Work is defined as the amount of energy required to move a force over a certain distance.
Where,
F = Force
d = distance
Our values are given as,
F = 1000N
d = 10m
Therefore replacing,
W = 1000*10
W = 10000J
Therefore the neccesary work is 10000J or 10kJ.
Answer:
37.725 A
Explanation:
B = magnitude of the magnetic field produced by the electric wire = 0.503 x 10⁻⁴ T
r = distance from the wire where the magnetic field is noted = 15 cm = 0.15 m
i = magnitude of current flowing through the wire = ?
Magnetic field by a long wire is given as
Inserting the values
i = 37.725 A
