A block goes on a wedge which in turns goes on a horizontal table, as given in figure. The wedge angle is Φ.
As long as the wedge is in met with table, we have the trivial constraints that the vertical acceleration of the wedge is zero. To find the constraint, let x be the horizontal co-ordinate
of the end of the wedge and let y and x be the horizontal and vertical coordinate of the block as given then
(x -X) = (h - y) cot Φ
Even if the friction among the block and wedge affect their acceleration, above relation is remains as long as they are in contact.
A wooden ring stand The bottom for this ring stand is made from a piece of wood 40 cm long, 15 cm wide and 1 cm thick. A whole 1 cm in diameter is bored by the centre of the ba
(i) Electric field lines come out of positive charge and go into the negative charge. (ii) Tangent to the field line at any point gives the direction of the field at that point.
The electrostatic shielding may be found by protecting and enclosing the sensitive instruments inside a hollow conductor due to inside hollow conductors, electric fields is zero.
