The charge imbalance that results from this movement of charge will generate an additional electric field in the region within t
he 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.
Note that the acceleration of the car between and () is constant. Initial velocity of the car was , whereas at . Hence, at , this car would have travelled a distance of:
.
At , the truck would have travelled a distance of .
In other words, at , the truck was ahead of the car. The velocity of the car is greater than that of the truck by . It would take another before the car catches up with the truck.
