At what point does a pilot in an aeroplane appear to be heaviest while performing a loop-the-loop in a vertical plane.

A pilot of mass 70 kg in a jet aircraft moves in a vertical circle while executing the loop-the-loop at a constant speed of 200 m/s. If the radius of the circle is 2.5 km what is the force exerted by the seat on the pilot at (a) the top of the loop and (b) the bottom of the loop.

A pilot does not fall down when his aeroplane loops the loop. Why ?

Current i flows through a long wire. A square loop made of conducting wire held below the wire in the same vertical plane is released and allowed to fall under gravity. If acceleration of the loop is a, then :

Assertion A conducting loop is rotated in a uniform magnetic field with constant angular velocity omega as shown in figure. At time t = 0, plane of the loop is perpendicular to the magnetic field. Induced emf produced in the loop is maximum when plane of loop is parallel to magnetic field. Reason When plane of loop is parallel to magnetic field, then magnetic flux passing through the loop is zero.

The two loops shown in the figure have their planes parallel to each other . A clockwise current flows in the loop X as viewed from X towards Y. The two coils will repel each other if the current in the loop X is :

A conducting square loop is placed in a magnetic field B with its plane perpendicular to the field. Now the sides of the loop start shrinking at a constant rate alpha. the induced emf in the loop at an instant when its side is a is

A square loop of side l iskept in a uniform magnetic field B such that its plane makes an angle alpha with vecB . The loop carries a current i. The torque experienced by the loop in this position is

In Fig, find the magnetic field at point P. The loop is lying in x-y plane.

A circular loop of flexible conducting material is kept in a magnetic field directed perpendicularly into its plane. By holding the loop at diametrically opposite points its is suddenly stretched outwards, then

A circular loop of radius R is kept in a uniform magnetic field pointing perpendicular into the plane of paper. When a current l flows in the loop, the tension produced in the loop is
