1 2 3 4 5 Interactive Exarr Zero Two point charges (q1 = -2.1uC and q2 = 6.2 uC) are fixed along the x- axis, separated by a distance d = 6.8 cm. Point P is located at (x,y) = Y (d,d). Be sure to use a vector approach to answer these problems. It P Standard'Exercis also helps limit the number of calculations since sometimes you can Electric F1: neglect one of the charge's effects due to its location relative to the point in question. d Standard Exercis Electric Fie WMWWMWM --------------.__' 1) What is EX(P), the value of the x-component of the electric field produced by q1 and q2 at point P? N/C Submit 2) What is Ey(P), the value of the y-component of the electric field produced by q1 and q2 at point P? N/C Submit A third point charge q3 = 2.6 uC is now positioned along the y-axis at a distance d = 6.8 cm from q as shown. What is EX(P), the x-component of the field produced by all 3 charges at point P? N/C Submit 4) Suppose all charges are now doubled (i.e., q1 = -4.2 uC, q2 = 12.4 uC, q3 = 5.2 uC), how will the electric field at P 'V' change? Its magnitude will increase by less than a factor of two and its direction will remain the same Its magnitude will increase by less than a factor of two and its direction will change Its magnitude will double and its direction will remain the same Its magnitude will double and its direction will change Submit 5) How would you change q1 (keeping qz and q3 fixed) in order to make the electric field at point P equal to zero? V Increase its magnitude and change its sign Decrease its magnitude and change its sign Increase its magnitude and keep its sign the same Decrease its magnitude and keep its sign the same There is no change you can make to q1 that will result in the electric field at point P being equal to zero.
