To determine the unknown weight of a body by the method of vector addition of forces (using rectangular components).
Apparatus Gravesand’s app., Two slotted weights with hanger. Plane mirror strip, Thread, Drawing pins, Plane paper, Protractor, Body of-unknown weight.Diagram Point to PonderVectors Those physical quantities which can be completely described by magnitude as well as specific direction are called vectors. e.g., force, torque, momentum etc. […]
To determine the value of ‘g’ by free fall method using electronic timer.
Apparatus Electronic free fall app. (Solenoid, Gate switch, Stand, Electronic timer, Metallic bob, leads) and meter rod. Diagram Point to Ponder Galileo was the pioneer worker to show that all bodies irrespective of their masses or nature falling freely in vacuum had the same acceleration at a given place. Everyone has observed the […]
To determine the area of cross-section of a wire or volume of small sphere using micrometer screw gauge
Apparatus: Micrometer screw gauge, Wire or sphere.Diagram: Point to Ponder The screw gauge is an instrument used to measure the thickness of very thin metal strip or the diameter of ball bearing. It is based upon the principle of a screw and consists of a U-shaped frame having a […]
To determine the volume of a cylinder using Vernier caliper
Apparatus: Vernier calipers, Solid cylinder. Diagram: Point to Ponder: Vernier callipers is used for measuring the length and diameter accurately up to 10 – 1 mm. A vernier callipers consists of a rectangular steel bars graduated in inches on one edge and in centimeters on the other edge this is known as the main scale. […]
