The charge imbalance that results from this movement of charge will generate an additional electric field in the region within the rod In what direction will this field point? A. It will point to the right and enhance the initial applied field B. It will point to the left and oppose the initial applied field

B. It will point to the left and oppose the initial applied field

Explanation:

Let the charge be positive and  and electric field be towards right . Charge will move towards right in the field due to which positive charge will accumulate towards right and excess of positive charge will lie there . This new charge distribution will create a field towards the left which is opposite to external electric field.

scientific laws are the result of testing theories and proving them to be facts.
