Answer:

$C=2.54\cdot 10^5\ F$

Explanation:

Energy Stored on a Capacitor

This energy is stored in the electric field present when a voltage V is applied to a capacitor C. It can be computed by the formula

$\displaystyle E=\frac{CV^2}{2}$

We can compute the energy by knowing the power dissipated in the flashlamp is P=8 W in a time of $7 \mu s=7\cdot 10^{-6}\ sec$

$\displaystyle E=\frac{P}{t}=\frac{8\ W}{7\cdot 10^{-6}\ sec}=1.14\cdot 10^6\ J$

Solving the first equation for C

$\displaystyle C=\frac{2E}{V^2}$

$\displaystyle C=\frac{2\times 1.14\cdot 10^6}{3^2}$

$\boxed{C=2.54\cdot 10^5\ F}$

How does charging by conduction occur?

lutik1710 [3]

Answer : (A) A charged object is brought near a neutral object without touching it.

Explanation:

Bodies can be charged by the method of conduction. By conduction the body acquires the same charge as on the charging body.

Charging the body can be understood by the following example of charging a paper cylinder by conduction. Make a paper cylinder by rolling a strip of paper on a pencil and then gently pulling out the pencil. Suspend the paper cylinder by a string tied to its center, now touch the paper cylinder with a glass rod rubbed with silk so it has a positive charge. Remove the class rod and the again bring it near to the paper cylinder.

The paper cylinder is repelled by the positively charged rod. And when you bring a negatively rubbed rod, next to the cylinder it will be attracted towards the rod. This means that the paper cylinder has acquired a positive charge as on the glass rod due to conduction.

Because it demonstrates the relationship between a body and the forces acting upon it, and its motion in response to those forces. [Hope that helps]
