a charged particle moves in a gravity free space without change in velocity. Which of the following is/are possible?

Does a single particle of a gas have temperature?

A particle moves in a gravity free space where an electric field of strength E and a magnetic field of induction B exit. Which of the following statement is are correct?

At what temperature will the particles in a sample of helium gas have an rms speed of 1.0 km//s ?

Sketch four magnetic field lines as obtained in a limited space on a horizontal plane in the earth's magnetic field alone.

Path traced by a moving particle in space is called trajectory of the particle. Shape of trajectiry is decided by the forces acting on the particle. When a coordinate system is associated with a particle motion, the curve equation in which the particle moves [y=f(x)] is called equation of trajectory. It is just giving us the relation among x and y coordinates of the particle i.e. the locus of particle. To find equation of trajectory of a particle, find first x and y coordinates of the particle as a function of time eliminate the time factor. The position vector of car w.r.t. its starting point is given as vec(r)=at hat(i)- bt^(2) hat(j) where a and b are positive constants. The locus of a particle is:-

In above question initial acceleration (i.e. (d^(2)vec(r))/(dt^(2))) of particle is, if r =at i ^ −bt 2 j ^:-

A particle of mass m moving eastward with a velocity V collides with another particle of same mass moving northwards with the same speed V . The two particles coalesce and the new particle moves in NE direction. Calculate magnitude and direction of velocity of new particle.
