t Print ill calculator i 4 Periodic Table Incorrect Incorrect Question 8 of 18 Incorrect Incorrect incorrect Map Consider the arrangement of charges shown in the figure below. Four charges of equal magnitude Q but varying sign are placed at the corners of a square as indicated. A positive charge q is placed in the center. What is the direction of the net force, if any, on the center charge? Indicate your answer by placing the appropriate label here: force O that the charge q were to be displaced slightly from the center position. On the figure to the right, label each box the arrow that best indicates the direction of the net force that would act on q if it were moved to that location. force

Explanation / Answer

For the first question, the charge at the center is in equilibrium i.e no net force acting on it because all the force get cancels out due to the equal charges at the opposite corners.

Now if the charge is moved slightly to the right the the the up arrow is the correct choice since the center charge is closer to the charges at the right corner the force on center chrge will be greater due to the right corner charges.The resultant of the +Qcharge at the bottom right and -Qcharge at the top right is upward direction as evident from the figure which shows the direction of force for each charge.
