A long solenoid carrying a current I is placed with its axis vertical as shown in the figure. A particle of mass m and charge q is released from the top of the solenoid. Its acceleration is (g being acceleration due to gravity)

A particle of mass 'm' and charge 'q' is accelerated through a potential difference of V volt, its energy will be

In the figure shown acceleration with which the mass m falls down when released is ( consider the string to be massless g-acceleration due to gravity )

An infinte wire having linear charge density lambda is arranged as shown in fig. A charge particle of mass m and charge q is released charged q is released from point P. Find the initial acceleration of the particle just after the particle is released.

An infinte wire having linear charge density lambda is arranged as shown in fig. A charge particle of mass m and charge q is released charged q is released from point P. Find the initial acceleration of the particle just after the particle is released.

A wire loop carrying a current I is placed in the xy-plane as shown in figure If a particle charge +Q and mass m is placed at in centre P and given a velocity v along NP (see figure), find its instaneous acceleration.

A particle of mass m performs vertical motion in a circle of radius r. Its potential energy at the highest point is ….. " " ( g is acceleration due to gravity)

A long wire carries a current of 20A along the directed axis of a long solenoid. The field due to a solenoid is 4mT . Find the resultant field at a point 3mm from the solenoid axis.
