Find the magnitude and direction of the torque acting on the square loop as shown in the diagram where B = 1.5 T along positive Z-axis.

What are the magnitude and direction of the electric field at the centre of square in figure if q=1xx10^4 C and a = 5cm.

Give the magnitude and direction of the net force acting on a stone of mass 0.1 kg, (a) just after it is dropped from the window of a stationary train,(b) just after it is dropped from the window of a train running at a constant velocity of 36 km/h,just after it is dropped from the window of a train accelerating with 1 ms^2,just after it is dropped from the window of a train accelerating with 1M/S2

Find the inclination to the positive X-axis of the tangent to the curve y= -3x- x^4 at the point where x=-1

(Attempt any nine of the following questions) There is an electric dipole on the x-y plane. Its dipole moment is 4 x 10^(-9) Cm . On . the same plane there is also a uniform electric field of magnitude 5x10^4 NC^(-1) . If the axis of the dipole makes an angle 30° with the electric field, calculate the magnitude of the torque acting on the dipole and also mention the di rection of torque.
