In many cases when we pull or push an object, we find that force and displacement are not in the same direction. Let a constant force F acting on a body produce a displacement S as shown in the figure. Let q be the angle between the direction of the force and displacemen..

Direct Current - When the current flows in the same direction it is called 'direct current' or DC The current derived from a cell or battery is unidirectional. So it is a DC source It is represented in an electrical circuit as The voltage V/s time graph f..

The water particles sticking to the cycle tyre are found to fly off tangentially Whenever a driver is negotiating a curve, the passengers experience a force acting away from the centre of the curve Inertia of a body depends upon its mass. That is, massive objects possess more inertia than li..

The direction of magnetic field around a current carrying conductor can be determined by using one of the laws given here. Rule Pictorial Representation Right Hand Thumb Rule Imagine that you are holding the conductor in your right hand with the fingers curled around it. I..

The direction of induced current can be determined by using Fleming's Right Hand Rule. Stretch the forefinger, the middle finger and the thumb of the right hand, such that they are mutually perpendicular to each other. If forefinger indicates the direction of the magnetic f..

If a coil carrying current is suspended by thin elastic long conductors, it will align itself as the compass needle, i.e., one end of the coil will point in the north direction and the other end will point towards the south. The polarity of the faces of the coil depends on the direc..

Newton's second law of motion states that rate of change of momentum is directly proportional to applied force and takes place in the same direction as the applied for..

Extend the thumb, forefinger, and the middle finger of the left hand in such a way that all the three are mutually perpendicular to each another. If the forefinger points in the direction of the magnetic field and the middle finger in the direction of the current, then, the thu..
