April Paper - Physics

1. A capacitor of capacitance C = 15 pF is charged with voltage V = 500 V. The electric field inside the capacitor with dielectric is 106 V/m and the area of the plate is 10– 4 m2, then the dielectric constant of the medium is: (

\({{\varepsilon }_{0}}=8.85\times {{10}^{-12}}\)
in SI units)

  1. a.12.47
  2. b.8.47
  3. c.10.85
  4. d.14.85

Solution:

  1. C = 15PF

    V = 500V

    E = 106 V/m

    A = 10– 4 m2

    \(C=\frac{k{{\varepsilon }_{0}}A}{d}\)

    \(d=\frac{k{{\varepsilon }_{0}}A}{C}\)

    E = V/d

    \(E= \frac{500 C}{k{{\varepsilon }_{0}}A}\)

    \(K=\frac{Vc}{A{{\varepsilon }_{0}}E}=\frac{500\times 15\times {{10}^{-12}}}{{{10}^{-4}}\times {{10}^{6}}\times 8.85\times {{10}^{-12}}}\)
    = 8.47

    Answer: (b)

      = 3.14 × 106 N/m2

      Answer: (c)

    28. A liquid of coefficient of viscosity

    \(\eta =1\)
    poise is flowing in a pipe of radius 3 cm on such that the rate of volume flow is 1000 / min. determine the Reynolds numbers.

    1. a. 3536
    2. b. 3500
    3. c. 3400
    4. d. 3600

    Solution:

    1. \(\eta\)
      = 1 poise

      r = 3 cm

      \(\frac{dv}{dt}=1000\,{}^{\ell }/{}_{\min }\)

      \(Reynolds Number {R}_{e}=\frac{\rho vD}{\eta }\)

      \(=\frac{1000}{0.1}\times \frac{1}{60\pi {{r}^{2}}}2r\)

      = 3536

      Answer: (a)
