we know that,
Due to a positive charged, the direction of electric field points away from the charge and due to a negative charge, the direction of the electric field points towards the charge hence the net electric field due to these two charges are as follows-

Suppose you place a charge q near a large metal plate. If q is attracted to the plate, is the plate necessarily charged? Yes, since only unlike charges can attract each other Yes, since only like charges can attract each other No, since a polarization charge could be induced in the plate No, since q can be attracted to an uncharged metal plate Question 8 (12.5 points) What would the electric field look like in a system with two parallel...
There is an infinitely large positively charged metal plate. On the right of the plate, two point-charges Q1 = -6.7 μC and Q2 = 1.8 μC are placed. The line connecting Q1 and Q2 is perpendicular to the charged plate. The distance between the plate and Q1 is D = 0.20 m, and the distance between Q1 and Q2 is d = 0.34 m. If the charge density in the plate σ is 1.3 μC/m2 , find the electric force...
2. The electric field outside a positively charged metal, but very near the surface, is σ/ε0. The electric field outside a single positively charged parallel (as in capacitor) plate is σ/2ε0. How can thinking about the problem of two positively charged parallel plates help to understand this problem?
2. The electric field outside a positively charged metal, but very near the surface, is o/Eo. The electric field outside a single positively charged parallel (as in capacitor) plate is 0/2€0.

Ground your electroscope. Touch a negatively charged rod to the metal plate of the electroscope. Draw in the schematic how the charges are distributed, and indicate the new deflection of the rotating pointer once it has come to equilibrium + Perform this experiment with the charge remaining from step 3. Recharge your negatively charged object and bring it into close proximity to the metal plate without touching. We are charging by induction in this case. How does the...

8) A proton is placed at rest near a positively charged plate. The proton is released and travels in the positive x direction. The proton reaches a velocity of 85000 m/s at the point when the potential is zero. (mproton = 1.67 x 10-27 kg, et = 1.6 x 10-19 C) a) What is the electric potential at the positively charged plate? A X b) The proton then enters a 9 T magnetic field directed into the page. Choose the...

Suppose we had a large, positively charged plate in an upright (vertical) position and a point charge with positive charge +Q. In lecture, you saw that a large charged plate gives rise to an electric field which is constant in space: we will call this electric field Eplate. Let us suppose also that we had a s bl with positive charge +q and mass m. The situation is depicted in Figure 1. +q,m +Q Figure 1 The objective of this...
