1Consider a water tank shown in the figure. It has one wall at x=Lx=L and can be taken to be very wide in the zz direction. When filled with a liquid of surface tension SS and density ρ\rho, the liquid surface makes angle θ0\theta_0 (θ0≪1\theta_0 \ll 1) with the xx-axis at x=Lx=L. If y(x)y(x) is the height of the surface then the equation for y(x)y(x) is: (take θ(x)=sin⁡θ(x)=tan⁡θ(x)=dydx\theta(x)=\sin\theta(x)=\tan\theta(x)=\frac{dy}{dx}, gg is the acceleration due to gravity) figure

Answer: B
3An electron (mass 9×10−319\times10^{-31} kg and charge 1.6×10−191.6\times10^{-19} C) moving with speed c/100c/100 (cc = speed of light) is injected into a magnetic field B⃗\vec B of magnitude 9×10−49\times10^{-4} T perpendicular to its direction of motion. We wish to apply an uniform electric field E⃗\vec E together with the magnetic field so that the electron does not deflect from its path. Then (speed of light c=3×108c=3\times10^8 m s−1^{-1})
  • A) E⃗\vec E is perpendicular to B⃗\vec B and its magnitude is 27×10427\times10^4 V m−1^{-1}
  • B) E⃗\vec E is perpendicular to B⃗\vec B and its magnitude is 27×10227\times10^2 V m−1^{-1}
  • C) E⃗\vec E is parallel to B⃗\vec B and its magnitude is 27×10227\times10^2 V m−1^{-1}
  • D) E⃗\vec E is parallel to B⃗\vec B and its magnitude is 27×10427\times10^4 V m−1^{-1}
Answer: B
4There are two inclined surfaces of equal length (L) and same angle of inclination 45° with the horizontal. One of them is rough and the other is perfectly smooth. A given body takes 2 times as much time to slide down, on rough surface than on the smooth surface. The coefficient of kinetic friction (µk)(µ_{k}) between the object and the rough surface is close to
  • A) 0.25
  • B) 0.40
  • C) 0.5
  • D) 0.75
Answer: D

  • A) 32\frac32
  • B) 23\frac23
  • C) 13\frac13
  • D) 12\frac12
