Electrostatic Potential and Capacitance — Physics STD 12 Science — Question

An arbitrary surface encloses a dipole. What is the electric flux through this surface?

Write any two characteristic properties of nuclear force.

Use the definition of linear pomentum from the previous question. Can we state the principle of conservation of linear pomentum for a single particle?

An electron and a proton are placed in a uniform electric field. Which will have greater acceleration and why?

A magnet of magnetic moment m is first cut perpendicular to its length and then perpendicular to its breadth into n equal parts, then calculate magnetic moment of each part.

Define the term electric dipole moment. Is it a scalar or a vector quantity?

Why does the bluish colour predominate in a clear sky?

What is the relation between drift velocity and relaxation time of free electrons in metals?

Answer the following question:
A charged particle enters an environment of a strong and non-uniform magnetic field varying from point to point both in magnitude and direction, and comes out of it following a complicated trajectory. Would its final speed equal the initial speed if it suffered no collisions with the environment?

What is the magnitude of alternating emf from peak to peak?
