1. Defined capacitance of a capacitor. If the radius of a spherical conductor is equal to sum of all digits of your registration
number (in meter) then find the capacitance of the spherical conductor.
2. Write the difference between electric field and electric potential. Four charges of each equal to positive charge of magnitude same as the sum of last two digits of your date of birth. If they are placed at four corners of a square of side x then find potential at center of square.
3. Explain electric flux and Gauss law for electrostatics. Two point charges of 40 C and 10 C respectively are placed 6 meter apart. Find the location of the neutral points from the charge of 10 C.
prompt: " sum of all digits of my registration number = 22"

Answer:
a) 2.41 km
b) 38.8°
Questions c and d are illegible.
Explanation:
We can express the displacements as vectors with origin on the point he started (0, 0).
When he traveled south he moved to (-3, 0).
When he moved east he moved to (-3, x)
The magnitude of the total displacement is found with Pythagoras theorem:
d^2 = dx^2 + dy^2
Rearranging:
dy^2 = d^2 - dx^2
The angle of the displacement vector is:
cos(a) = dx/d
a = arccos(dx/d)
a = arccos(3/3.85) = 38.8°
