Derive an expression for the acceleration of the car. Express your answer in terms of D and vt Determine the time at which the s

B. The charge on A is -q; B has no charge. Given that a positive charge is situated at the center of an uncharged metallic sphere which is insulated and disconnected from the ground, a negative charge (-q) will appear on the inner surface A of the sphere. Should the exterior surface B be grounded, it will become neutral, resulting in no charge remaining on surface B.

Answer:

The excess charge is

Explanation:

According to the question, we are informed that

The diameter is

The potential of the surface is

The radius of the sphere is

by plugging in given values

The potential at the surface is mathematically expressed as

Where k is Coulomb's constant with a value

Based on the question stating there are no other charges, Q represents the excess charge

Therefore

inserting the numerical values

assuming north-south is along the Y-axis and east-west along the X-axis

X = total X-displacement

from the graph, total displacement in the X-direction is computed as

X = 0 - 20 + 60 Cos45 + 0

X = 42.42 - 20

X = 22.42 m

Y = total Y-displacement

from the graph, total displacement in the Y-direction is computed as

Y = 40 + 0 + 60 Sin45 + 50

Y = 90 + 42.42

Y = 132.42 m

To calculate the magnitude of the net displacement vector, we apply the Pythagorean theorem, yielding

magnitude: Sqrt(X² + Y²) = Sqrt(22.42² + 132.42²) = 134.31 m

Direction: tan⁻¹(Y/X) = tan⁻¹(132.42/22.42) = 80.4 deg north of east

Broad questions addressed by conducting this experiment involve the effects of electric current.

Additional details

Electric current measures the quantity of electric charge passing per unit time.

It results from electrons moving due to a voltage difference (high potential to low potential) between two points.

These electrons flow through wires acting as conductors.

Ohm's Law states that:

The potential difference across a conductor is proportional to the current flowing through it, assuming resistance remains the same.

A basic electrical circuit consists of a voltage source (battery) and a lamp.

Ammeters used to measure current must be connected in series with the load.

By adjusting the voltage while resistance is constant, varying current values are observed; increasing voltage produces higher current.
