Explanation:
Answer:
There will be no change in the direction of the electric field .
Explanation:
The direction will remain the same because the sign of the charges has no effect on it.
When one replaces the conducting cube with one that has positive charge carriers there will be no change in the direction of the field as there is no defined relationship between the direction of the electric field and sign of the charge.
Answer: The answer to the question is 0.25 ohms
Explanation:
R = u x/A .......1
where u is chosen as the resistivity of
the rod, A is area of the rod and x is
chosen as the length of the rod.
Let R* be the resistance of the
lengths of the rod across the adjoints
Then R* = u1/4.......2
Comparing equation 1 and 2
R* = 1/4
=0.25ohms
