Answer:
50000 μT
Explanation:
From the given information:
the diameter of the loop = 1.0 mm = 0.001 m
no of turns (N) = 200
current (I) = 0.199 A
radius = d/2 = 0.001/2
= 5 × 10⁻⁴ m
Recall that;
the magnetic field at the centre of circular wire is:
= 0.05 T
= 50000 μT
Since the centre of the earth's magnetic field is given to be equal to the magnetic field produced by the wire, then:
the earth's magnetic field = 50000 μT
Answer:
initial magnitude will be 9 N and direction will be to the right
Explanation:
force= 9N
mass m= 330 grams
acceleartion = a
from newtons 2nd law of motion we write
dP is the chage in momentum dt is time taken and F is the Force applied
this shows that the rate of change of momentum is 9 N
we also know that F= ma
putting values we get
a= 27.27 m/sec^2
The direction of acceleration will along the direction of force applied. So will be the direction of change momentum as in F=ma, mass is the scalar quantity and direction of force dictates the direction of motion. Hence, initial magnitude will be 9N and direction will be to the right
