Assignment I
1- Consider three point charges located at the corners as shown in fig.
Where \( q_{1}=q_{3}=5 \mu \boldsymbol{C}, q_{2}=-2 \mu C \) and \( \boldsymbol{a}=0.1 \mathrm{~m} \), Find the resultant force exerted on \( \boldsymbol{q}_{2} \) (magnitude and direction)
2- At what distance from a point charge of \( 8 \mu \mathrm{C} \) would the potential \( \mathrm{V} \) equal
\[
3.6 \times 10^{4} \mathrm{~V} \text { ? }
\]
3- In the circuit shown \( \mathrm{V}=48 \mathrm{~V}, \mathrm{C}_{1}=9 \mu \mathrm{F}, \mathrm{C}_{2}=4 \mu \mathrm{F} \) and \( \mathrm{C}_{3}=8 \mu \mathrm{F} \).
(a) determine the equivalent capacitance of the circuit,
(b) determine the energy stored in the combination by calculating the energy stored in the equivalent capacitance,
