A conductor has free electrons, and they experience a force only when the electric field is not zero. In a static situation, the free electrons gets itself distributed in such a way that, the electric field everywhere inside the conductor is zer..

When an electric current flows in a closed loop of wire, placed in a uniform magnetic field, the magnetic forces produce a torque which tends to rotate the loop so that area of the loop is perpendicular to the direction of the magnetic field. Consider a rectangular coi..

If the electric field is not normal to the surface, then it would have same non-zero component along the surface. The free charges on the surface would then experience a force and move. In a static situation, electrostatic field should not have tangential component, w..
The force required to stop a moving body is directly proportional to its velocity.
Thus the quantity of motion in a body depends on mass and velocity of the body. This quantity of motion defines a new physical quantity called momentum. The momentum of an object is defined as the product of its mass and its velocity. Momentum is a vector quantity and its direction wi..

This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
Looking for More Help!
