The magnitude of the force experienced by a 1. 0 c charge placed at the location of the test charge is 4.5*10^8N.
To find the answer, we have to know more about the force experienced between two charges.
<h3>How to find the
force experienced between two charges?</h3>

- We have to find the force experienced between two charges,

where, k=8.99*10^9.
- Thus, by substitution, the force will be,

Thus, we can conclude that, the magnitude of the force experienced by a 1. 0 c charge placed at the location of the test charge is 4.5*10^8N.

Answer:

Explanation:
The speed of the actor before the collision is found by means of the Principle of Energy Conservation:



The speed after the inelastic collision is obtained by using the Principle of Momentum Conservation:


Lastly, the maximum height is determined by using the Principle of Energy Conservation again:



Answer:
Explanation:
We shall apply Doppler's effect here .
original frequency = 79.79 kHz
apparent frequency due to movement of source ( bat ) = 81.63 Hz
Let the velocity of bat be v .
expression for apparent frequency can be given as follows
n = 
n is apparent frequency , n₀ is original frequency , V is velocity of light and v is velocity of source of sound
Putting the values
81.63 = 
340-v = 332.33
v = 7.67 m /s
velocity of bat is 7.67 m /s .
The intensity of the magnetic force exerted on the wire due to the presence of the magnetic field is given by

where
I is the current in the wire
L is the length of the wire
B is the magnetic field intensity

is the angle between the direction of the wire and the magnetic field
In our problem, L=65 cm=0.65 m, I=0.35 A and B=1.24 T. The force on the wire is F=0.26 N, therefore we can rearrange the equation to find the sine of the angle:

and so, the angle is
