Newton's / Coulomb's Law Demonstration
Study the concepts of Newton?s and Coulomb?s laws with this apparatus. This apparatus can be used to demonstrate repulsion, attraction of charged bodies and provides the ability to measure the angle between the 2 strings and thus the force between the two charged spheres. The charge can be provided by a Wimshurst machine or a Van de Graff generator or by simply rubbing a plastic rule with on a duster. Includes manual.

Optical Disc
A 500 mm diameter disc marked every 5° is mounted on a heavy stand and is rotatable around its centre. It can be held in any desired position. The lamp house, with a 12V 24 W special filament lamp has rotatable slots to provide light beams of varying widths and also narrow single, double and triple beams. Attached to the lamp house is an adjustable lens carrier with lens to provide diverging, parallel or converging light beams which are clearly visible in classroom. The lamp house can be held in any desired position around the disc. Optical elements are two 50 x 25 mm plane glass mirrors, and a metallic cylindrical mirror, each mounted in a holder, for reflection. For refraction, 20 mm thick acrylic semi-circular block, bi-convex lens, bi-concave lens each 140 mm long and a trapezium with 125 mm base are provided. Each of these elements has embedded magnets to hold on to the disc.
