When a charged particle enters a magnetic field at an angle of $60°$ with the field direction, it traces

The velocity vector of a proton is directed perpendicular to the plane of a current loop at its centre $O$ as shown in the figure. What will be the force acting on the proton at the centre of the loop?

The figure shows two infinitely long and this parallel wires $P$ and $Q$ placed $0.2 \mathrm{m}$ apart perpendicular to the plane of the paper, carrying equal currents of $20 \mathrm{A}$  each. Find the magnetic field at a point $R$, at a distance of $0.2 \mathrm{m}$ from both the wires. The symbol $\otimes$ indicates that the current is directed inward.

To convert a galvanometer into a voltmeter, we must connect a

Figure shows a circular coil with centre ‘O’. If current flows through the coil, the magnetic field produced by it is maximum at :

The figure shows four directions for the velocity vector v of a positively charged particle. It is moving through a uniform electric field E, directed normally out of the page and a uniform magnetic field B as shown :

Which direction of motion will give the particle the greatest net force ?

The figure shows four directions for the velocity vector v of a positively charged particle. It is moving through a uniform electric field E, directed normally out of the page and a uniform magnetic field B as shown :

Motion in which direction may result in net force zero on the particle.

The figure shows four directions for the velocity vector v of a positively charged particle. It is moving through a uniform electric field E, directed normally out of the page and a uniform magnetic field B as shown :

Write the equation for the speed of the charged particle when it moves undeflected in the field.
