The angular magnification of the microscope is 78.125.
<h3>What is angular magnification?</h3>
the ratio of the angle at the eye that an optical instrument's image occupies to the angle at the eye that an object occupies while not being viewed through an optical instrument is called as angular magnification.
Thus we can calculate it as:
- focal length of objective lens, fo = 1.6 cm
- focal length of the eyepiece, fe = 2.5 cm
- Distance between the lenses, L = 15 cm
- Least distance of distinct vision for normal eye, d = 25 cm
The formula for the magnification of the compound microscope is given by
M = - 78.125
Thus, the magnification of the compound microscope is 78.125.

Answer:
Explanation:
The magnitude of the net force exerted on q is known, we have the values and positions for and q. So, making use of coulomb's law, we can calculate the magnitude of the force exerted by on q. Then we can know the magnitude of the force exerted by about q, finally this will allow us to know the magnitude of
exerts a force on q in +y direction, and exerts a force on q in -y direction.
The net force on q is:

Explanation:
Mass of the diskshaped grindstone, m = 1.1 kg
Radius of disk, r = 0.09 m
Angular velocity,
Time, t = 42.4 s
We need to find the frictional torque exerted on the grindstone. Torque in the rotational kinematics is given by :
I is moment of inertia of disk,
So, the frictional torque exerted on the grindstone is .
