It depends on the objects chemical composition.
Answer:
B = 0.031T
Explanation:
Given n1 = 1000turn/m
i1 = 25A
μo = 4π ×10‐⁷ Wb/A•m
B1 = μo×i1×n1
B1 = 4π ×10‐⁷ × 25 × 1000 = 0.031T.
Answer:
option b
Explanation:
There is an object pulled inward in an electric field.
We have to find out of the four options given which is true.
a) The object has a neutral charge is false since when electric field pulls the object inward, there is a charge inside.
b) The object has a charge opposite that of the field, this option is correct since there will be an equal and opposite charge created by the object
c) The object has a negative charge will be correct only if the original charge was positive hence wrong
d) The object has a charge the same as that of the field is incorrect since this would be opposite the charge
So only option b is right
