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:
d.) Marbles 1 and 2 repel each other, but no interaction occurs with marble
Explanation:
Rubbing the glass against the silk charges the glass positively.
Assuming polarization is ignored,
●Glass won't conduct electrical charge. Therefore, acting as a insulator.
●neutral objects won't distribute it's charge when affected by charge objects in proximity. Therefore, over the marble surface, the charge remain spherically symmetrical (undisturbed)
Marble 1 is positive
Marble 2 is positive
Since marble 1 and 2 are positive, repulsion will occur.
marble 3 is neutral (still assuming polarization is ignored), therefore, no interaction with marble 1 and 2
