A graph of the electric field is shown. What is the voltage at x=4m, assuming the initial voltage at the origin x=0 was V=-30V? Be very careful with your signs. E 20% x=y

Find the voltage change when an electric field does 13 JJ of work on a 0.00011-CC charge. Express your answer to two significant figures and include the appropriate units.   Find the voltage change when the same electric field does 26 JJ of work on a 0.00022-CC charge. Express your answer to two significant figures and include the appropriate units.

for -6.9V Use equations for the V of point charge to calculate and verify for this voltage value. Using the distance scale and the measuring tape to find the distance from your meter to each charge. The measured distance between both charges is 554.2cm.

An electron is fired at a speed vi = 3.1 × 106 m/s and at an angle θi = 36.8° between two parallel conducting plates as shown in the figure. If s = 1.8 mm and the voltage difference between the plates is ΔV = 98.8 V, determine how close, w, the electron will get to the bottom plate. Put your answer in meters and include at 6 decimal places in your answer. Do not include units. The x-axis of the coordinate system is in the middle of the parallel plate capacitor

For the circuit shown, AVbattery = 28 V, R₁ = 5.0 02, R₂ = 5.0 2 and C= 4.5 F. The capacitor is initially uncharged and the switch is open. What is the charge on the capacitor a long time after the switch is closed, in Coulomb? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. R₁ www R₂ www C
