What is nuclear binding energy? State and explain
Heisenberg uncertainty principle.
State and explain photo-electric effect. A photo
electric surface has a work function of 6 eV and photo
electron frequency 1015𝐻𝑧.What is the maximum
velocity of photo electron?
Find the relationship between the mass, total energy,
rest energy and the momentum. A particle is moving
with a speed 1 2 𝑐.Calculate the ratio of its rest mass
and the mass which in motion.

What is Electric flux? What is the electric field
intensity in a conductor and why?
A parallel plate air field capacitor having area 20 cm2 and
plate spacing 2 mm is charged to a potential difference of
300v.Find (i) the capacitance, (ii) the magnitude of the
charge on each plate, (iii)the stored energy.

What's amperes law? Why did Maxwell modify it?
Consider a rectangular loop of wire of length 20m and
width 10m which sits in a region of magnetic field
50(T) and the angle between the field and area is 60◦.
