Answer:
In a two particle system, the center of mass lies on the center of the line joining the two particles.
Explanation:
Formula which holds true for a leans with radii and and index refraction n is given as follows.
Since, the lens is immersed in liquid with index of refraction . Therefore, focal length obeys the following.
and,
or,
= 32.4 cm
Using thin lens equation, we will find the focal length as follows.
Hence, image distance can be calculated as follows.
= 47.9 cm
Therefore, we can conclude that the focal length of the lens in water is 47.9 cm.
We have that the amount of the charge q is
From the Question we are told that
Force
Velocity
Angle
Magnetic field
Generally, the equation for Force F is mathematically given by
In conclusion
The amount of the charge q is

In a fluid, all the forces exerted by the individual particles combine to make up the pressure exerted by the fluid
Due to fundamental nature of fluids, a fluid cannot remain at rest under the presence of shear stress. However, fluids can exert pressure normal to any contacting surface. If a point in the fluid is thought of as a small cube, then it follows from the principles of equilibrium that the pressure on every side of this unit of fluid must be equal. but if this were not a case, the fluid would move in the directions of the resulting force, So the pressure on a fluid at rest is isotropic.
