A 10 g bullet having a charge of 4.00 μC is fired at a speed of 270 m s−1 in a horizontal direction. A vertical magnetic field of 500 μT exists in the space. Find the deflection of the bullet due to the magnetic field as it travels through 100 m. Make appropriate approximations.
We know,
F=q(V×B)
m α = q VB
α=qVBm
Time taken to travel 100 m distance in horizontal
i=Sv=100270 sec.
So, in this time intervel bullet deflection is
y=12 at2
=12×4.00×10−6×270×500×10−610×10−3×(100270)2
=3.7×10−6 m.
