Answer:
I believe he shouted eureka after he stepped into a bath and noticed that the water rose. He then realized that the volume of water displaced must be equal to the volume of the part of his body he had submerged

Explanation:
given
R = 1.5 cm
object distance, u = 1.1 cm
focal length of the ball, f = -R/2
= -1.5/2
= -0.75 cm
let v is the image distance
use, 1/u + 1/v = 1/f
1/v = 1/f - 1/u
1/v = 1/(-0.75) - 1/(1.1)
v = -0.446 cm <<<<<---------------Answer
magnification, m = -v/u
= -(-0.446)/1.1
= 0.405 <<<<<<<<<---------------Answer
The image is virtual
The image is upright

Kindly check the diagram in the attached image below.
By applying Coulomb's law between the charges, the net force on the charged particle q₁ due to particle q₂ and q₃ is -9.86 N.
<h3>
Distance between q₂ and q₃</h3>
The distance between the second charge and the third charge is given as;
r = 0.3 m
<h3>Force on q₂ due to q₃</h3>

<h3>Net force on particle q₁</h3>
The net force on particle q₁ is determined by summing the individual forces together;
F(net) = F₁ + F₂
F(net) = -14.4 + 4.54
F(net) = -9.86 N
Thus, by applying Coulomb's law between the charges, the net force on the charged particle q₁ due to particle q₂ and q₃ is -9.86 N.

Answer:
<em>F</em> = <em>0</em>
Explanation:
This problem can be solved by using the equation for the force produced by a magnetic field over a charge
<em>F</em> = q<u><em>v</em></u> X <em>B</em>
That is, the cross product between velocity and the magnetic field.
In this case, v is in the negative z-direction <em>v</em> = -v k^,
and the magnetic field is in the positive z-direction <em>B</em> = z k^
Hence, the cross product is
F = q<em>v </em>X <em>B</em> = 0i^ - 0j^ + 0k^ = <em>0</em>
In this case the net force is zero due to both velocity and magnetic field vectors are in the z-direction
