Experiment Topics

Experiment 1
Determination of area of cross section of cylinder using slide calipers
  • Determination of radius of cross-section of a wire with screw gauge and hence find it's area of cross section
  • Fixed lomba scale ta main scale/linear scale and jeita ghurano jay, circular scale.
  • place the wire in between the screw, turn round the ratchet so it gets fixed, beshi jore fix koiro na
  • Linear scale readings er sob same asar kotha, cirluar scale +-5
  • Least count
    = small scale of main scale ⁄ Total division of circular scale
    =0.5⁄50
    = 0.01mm
  • Value of circular scale = least count * circular scale divisions
  • Total readings = Value of circular scale + linear scale readings
  • Diameter = mean of total readings
  • Mean radius = d/2 mm and cm duita tei show korte hobe, cm diye baki kaj
  • Area of cross section, A = 𝜋*r2
  • Result in cm2
Experiment 2
Determination of area of cross section of wire using screw guage
  • Determination of radius of cross-section of a wire with slide calipers and hence find it's area of cross section
  • Fixed lomba scale ta main scale/linear scale and jeita narano jay, vernier scale.
  • akta ball dibe, seta measuring jaw te rakhte hobe
  • Linear scale reading(mm)main and vernier er measurement er daag ase, konta perfectly 180 degree hoy dekhte hobe,
  • linear scale reading +-1 or +-2 beshi na niye bhalo, vernier onek different hoite pare
  • Vernier scale divisions, vernier scale e 0 baad diye oi 180 degree parallel line porjonto sob line gonte hobe, (just double)
  • Least count/vernier constant(mm)
    = small scale of main scale ⁄ Total division of vernier scale
    =1⁄20
    = 0.05mm
  • Vernier scale reading(mm) = vernier constant * vernier scale divisions
  • Total reading(mm) = linear scale reading + vernier scale reading
  • Diameter(mm) is mean of total reading
  • mean readius = d/2 in both mm and cm
  • Calculations
  • Area of cross section, A = 𝜋*r2
  • Result in cm2
Experiment 3
Determination of acceleration due to gravity using simple pendulum
Experiment 4
Determination of acceleration due to gravcity by using compound pendulum
Experiment 5
Determination of spring constant and effective mass using SHO
Experiment 6
Determination of the radius of curvature by using spherometer
Experiment 7
Determination of refractive index using pin method
Experiment 8
Determination of focal length and power of convex lens using displacement method
Experiment 9
Determination of focal length and power of concave lens using auxillrary method
