Question

Each sketch below shows three objects with an electric charge. In each case, decide whether there is a net force acting on the object outlined in green. If there is a net force, decide whether it pushes the green-ring object to the left or right. Then select the appropriate button under the sketch. For example, if there is a net force pushing the green-ring object in the first sketch to the left, select the left button under the first sketch. If there is no net force on the green-ring object in the second sketch, select the middle button under the second sketch. And so on

Explanation / Answer

Ans :

According to the general rule , the like charges repel and opposite charges attract each other.

The attraction and repulsion forces between the charges particles is directly proportional to the amount of charges present on the ions and inversely proportional to the distance in between them.

So here :

1) Since the all the charges are positive here , the green ring object faces more repulsion from +3 ion , and hence move towards right.

2) Here the green ring object is positively charged , so it gets attracted towards -2 charge , i.e. towards right side.

3) The green ring object gets attracted towards -3 charged ion sice it is more in magnitude, hence the object move towards left.
