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:
acceleration a = 1.04 m/s2
Explanation:
Assume the train has a speed of 23m/s when the last car passes the railway workers. Once this happens the last car would have traveled a total distance of the 180m distance between the railway worker standing 180 m from where the front of the train started plus the 75m distance from the first car to the last car:
s = 75 + 180 = 255 m
We can use the following equation of motion to find out the distance traveled by the car:
where v = 23 m/s is the velocity of the car when it passes the worker,
= 0m/s is the initial velocity of the car when it starts, a m/s2 is the acceleration, which we are looking for.
