In forward biasing of the - junction:

  1. A
    The positive terminal of the battery is connected to -side and the depletion region becomes thin
  2. B
    The positive terminal of the battery is connected to -side and the depletion region becomes thick
  3. C
    The positive terminal of the battery is connected to -side and the depletion region becomes thin
  4. D
    The positive terminal of the battery is connected to -side and the depletion region becomes thick

Solution & Step-by-step Explanation

Forward bias occurs when the -type region is connected to the positive terminal and the -type region to the negative terminal. This setup opposes the built-in potential, pushing carriers towards the junction and reducing the width of the depletion region.

Consider a water tank as shown in the figure. It has one wall at x = L and is very wide in the z direction. When filled with a liquid of surface tension S and density ρ , the liquid surface makes an angle θ_0 ( θ_0 1 ) with the x -axis at x = L . If y(x) is the height of the surface, then the equation for y(x) is:(Take θ(x) ≈ θ(x) ≈ θ(x) = dy/dx and g as acceleration due to gravity) ![image](https://pub-7faa453bd1ec4bf0a04cc031c6f058de.r2.dev/images/e48999a7-2b29-4d5c-be16-ae2fd5fbcea5.png)

An electron (mass 9 × 10^-31 kg and charge 1.6 × 10^-19 C ) moving with speed c/100 ( c = speed of light) is injected into a magnetic field B of magnitude 9 × 10^-4 T perpendicular to its direction of motion. We wish to apply a uniform electric field E together with the magnetic field so that the electron does not deflect from its path. Then (speed of light c = 3 × 10^8 ms^-1 ):

There 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 ( μ_k ) between the object and the rough surface is close to:
