Let's see
Momentum be P
On comaparing
- c=1
So
- b-3c=1
- b-3=1
- b=1+3
- b=4
and
- -a-b=-1
- -a-4=-1
- -a=-1+4=3
- a=-3
So the unit is
- DV⁴/F³
Answer:
The electric current in the wire is 0.8 A
Explanation:
We solve this problem by applying the formula of the magnetic field generated at a distance by a long and straight conductor wire that carries electric current, as follows:
B= Magnetic field due to a straight and long wire that carries current
u= Free space permeability
I= Electrical current passing through the wire
a = Perpendicular distance from the wire to the point where the magnetic field is located
Magnetic Field Calculation
We cleared (I) of the formula (1):
Formula(2)
a =8cm=0.08m
We replace the known information in the formula (2)
I=0.8 A
Answer: The electric current in the wire is 0.8 A
