Two point charges Q1 = 3.5 μC and Q2 = 7.5 μC are initially very far apart. They are then brought together with a final separation of 2.5 m. How much work does it take to bring them together?
Added by Gina A.
Step 1
5 \times 10^{-6} \, \text{C} \) (charge of Q1) \( Q_2 = 7.5 \times 10^{-6} \, \text{C} \) (charge of Q2) \( r = 2.5 \, \text{m} \) (final separation) Show more…

Two-point charges Q1 = 4.5 μC and Q2 = 8.5 μC are initially very far apart. They are then brought together, with a final separation of 3.5 mm. How much work does it take to bring them together?

How much work is required to completely separate two charges (each -1.25 μC) and leave them at rest if they were initially 6.0 mm apart?
Ivan K.
Two large, parallel conducting plates carrying opposite charges of equal magnitude are separated by 2.20 $\mathrm{cm}$ . (a) If the nsurface charge density for each plate has magnitude 47.0 $\mathrm{nC} / \mathrm{m}^{2}$ , what is the magnitude of $\overrightarrow{\boldsymbol{E}}$ in the region between the plates? (b) What is the potential difference between the two plates? (c) If the separation between the plates is doubled while the surface charge density is kept constant at the value in part (a), what happens to the magnitude of the electric field and to the potential difference?
