Whether the diffraction effects from a slit will be more clearly visible or less clearly, if the slit-width is increased?

Sketch graph to show how charge Q given to a capacitor of capacitance C varies with the potential difference.

It is proposed to move a particle in simple harmonic motion on a rough horizontal surface by applying an external force along the line of motion. Sketch the graph of the applied force against the position of the particle. Note that the applied force has two values for a given position depending on whether the particle is moving in positive or negative direction.

Which rules are followed in nuclear reactions?

Consider a 10cm long portion of a straight wire carrying a current of 10A placed in a magnetic field of 0.1T making an angle of 53° with the wire. What magnetic force does the wire experience?

Describe briefly, with the help of a diagram, the role of the two important processes involved in the formation of a p-n junction.

When an electron revolving in its lowest energy level in the hydrogen atom moves to the third excited state, how is the de Broglie wavelength associated with it affected?

Think over the experiment number 2 of Faraday and Henry and tell :
(a) What will you do to obtain more deflection in the galvanometer?
(b) How will you show the presence of current in the absence of a galvanometer?
