Two electric charges, held a distance, d, apart experience an electric force of magnitude, F, between them. If one of the charge

Aneli [31]

Answer:

When one of charge is doubled, the magnitude of the force between them gets doubled.

Explanation:

The electric force between two electric charges is given by :

$F=k\dfrac{q_1q_2}{d^2}$

Here,

k is the electrostatic force

d is the separation between charges

$q_1\ and\ q_2$ are charges

If one of the charges is doubled in magnitude while maintaining the same separation between the charges, $q_1'=2q_1$

New force becomes,

$F'=k\dfrac{q_1'q_2'}{d'^2}$

$F'=k\dfrac{(2q_1)q_2'}{d'^2}$

$F'=2k\dfrac{q_1q_2'}{d'^2}$

When one of charge is doubled, the magnitude of the force between them gets doubled. Hence, this is the required solution.

A housefly walking across a clean surface can accumulate a significant positive or negative charge. In one experiment, the large

Lisa [10]

Answer:

$4.56*10^8 \text{ electrons.}$

Explanation:

Since the fly accumulated a positive charge of +73pC, it must have lost an equal number of negative charge of -73pC to the surface (because the housefly was neutral to begin with).

Therefore, to answer our question we have to ask ourselves <em>how many electrons combine to make -73pC of charge? </em>

The answer is since one electron carries a charge of $-1.6*10^{-19}C$ , the number $n$ of electrons that make up -73pC $(-73*10^{-12}C)$ are

$n= \dfrac{-73*10^{-12}C}{-1.6*10^{-19}C/e}$

$\boxed{n= 4.56*10^8e.}$

Thus, the housefly lost about 456 million electrons to the surface!

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.6 multiply 1010 m (inside t

Doss [256]

We will apply the concepts related to energy conservation to develop this problem. In this way we will consider the distances and the given speed to calculate the final speed on the path from the sun. Assuming that the values exposed when saying 'multiply' is scientific notation we have the following,

$d_1 = 4.6*10^{10}m$

$v_i = 9.3*10^4m/s \rightarrow \text{Initial velocity comet}$

$d_2 = 6*10^{12}m$

The difference of the initial and final energy will be equivalent to the work done in the system, therefore

$E_f = E_i +W$

$K_f +U_f = K_i +U_i + 0$

$\frac{1}{2} mv_f^2+\frac{-GMm}{d_2} = \frac{1}{2} mv_i^2+\frac{-GMm}{d_1}$

Here,

m = Mass

$v_f$ = Final velocity

G = Gravitational Universal Constant

M = Mass of the Sun

m = Mass of the comet

$v_i$ = Initial Velocity

Rearranging to find the final velocity,

$v_f = \sqrt{v_i^2+2GM(\frac{1}{d_2}-\frac{1}{d_1})}$

Replacing with our values we have finally,

$v_f = \sqrt{(9.3*10^4)+2(6.7*10^{-11})(1.98*10^{30})(\frac{1}{6*10^{12}}-\frac{1}{4.6*10^{10}})}$

$v_f = 75653.9m/s$

Therefore the speed is 75653m/s
