Pick out the two scalar, quantities in the following list: force, angular momentum, work, current, linear momentum, electric field, average velocity, magnetic moment, relative velocity.

Establish a relation between angular momentum, moment of inertia and angular velocity.

State, for each of the following physical quantities, if it is a scalar or a vector: volume, mass, speed, acceleration, density, number of moles, velocity, angular frequency, displacement, angular velocity.

Find the following expression for the magnetic moment of an electron moving in a circular path mu_c = c/(2m_c) 1 Wherel is the angular momentum of the electron about the nucleus, e and m_c are its charge and mass.

An electron is moving with a velocity (3hati+3 hatj)ms^(-1) in an electric field 3hat i+6hat j+2hat k and a magnetic field 2hat j+3 hat k . Calculate the magnitude of the force.
