Calculating Distance Deflected by Earth's Magnetic Field for 3.4g Bullet

AI Thread Summary
To calculate the deflection of a 3.4g bullet moving at 160 m/s in Earth's magnetic field, the formula r = mv/qB is applicable, where m is mass, v is velocity, q is charge, and B is the magnetic field strength. The bullet's charge is 13.5 x 10^-9 C and the magnetic field strength is 5 x 10^-5 T. The confusion regarding the angle is unnecessary since the bullet's motion is perpendicular to the magnetic field. After traveling 1 km, the deflection can be determined using the correct application of the formula. The problem was ultimately resolved with the right approach to projectile motion.

A 3.4g bullet moves with a speed of 160 m/s perpendicular to the Earth's magnetic field of 5x10^-5T. If the bullet possesses a net charge of 13.5 x 10^-9 C, by what distance will it be deflected from its path due to the Earth's magnetic field after it has traveled 1 km?

I am confused. Do I use r=mv/qB? Do I need an angle? I am confused by the way this question is phrased. Plsease help!

Thanks.

i forget the exact way of doing this problem, but i remember that it involves projectile motion
 
Thanks so much for your input. I solved it, you were right. :)

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
