Q2.An electron moves straight
inside a charged parallel plate capacitor of uniform charge density σ. The time
taken by the electron to cross the parallel plate capacitor when the plates of
the capacitor are kept under constant magnetic field of induction is

Q3.The force experienced by a
particle having mass m and charge q accelerated through a potential difference
V when it is kept under perpendicular magnetic field is

Q5.A thin insulated wire forms
a plane spiral of N = 100 tight turns carrying a current I = 8 m A (milli
ampere). The radii of inside and outside turns are a = 50 mm and b = 100 mm
respectively. The magnetic induction at the center of the spiral is

Q6.Three wires of equal lengths are bent in the form of loops. One of the loops is circle, another is a semi-circle and the third one is a square. They are placed in a uniform magnetic field and same electric current is passed through them. Which of the following loop configuration will experience greater torque ?

Q7.Two identical coils, each
with N turns and radius R are placed coaxially at a distance R as shown in the
figure. If I is the current passing through the loops in the same direction,
then the magnetic field at a point P which is at exactly at R/2 distance
between two coils is

Q10.A non-conducting charged
ring ofcharge q, mass m and radius r is rotated with constant angular
speed ω. Find the ratio of its magnetic moment with angular momentum is
