Question
A ball is thrown vertically up with a velocity of 20m/s. Construct acceleration time and displacement time graph.
✓
Answer
u = 20ms-1, a = g ms-2 Time to reach the highest point, $\text{t}=\frac{\text{u}}{\text{g}}=2\text{ seconds}.$ Max. height $=\frac{1}{2}\text{g}\times4=20\text{m}$

Figure shows a conducting square loop placed parallel to the pole faces of a ring magnet. The Pole-faces have an area of 1cm2 each and the field between the poles is 0.10T. The wires making the loop are all outside the magnetic field. If the magnet is removed in 1.0s, what is the average emf induced in the loop?
