Explanation / Answer

Given that

charge q=-6.5*10^-17 C

mass m=1.1*10^-26 kg

speed v=460 m/s

magnetic field B=0.25

(a) ans the direction of the magnetic force is under negative y-direction

(b)&(c) ans

now we find the magnetic force

magnetic force F=Bqvsin(theta)=0.25*460*-6.5*10^-17sin(270)=747.5*10^-17 N

(d) ans

the motion of the charge is circular motion

(e) the centripetal acceleration ac=F/m

(f) ans :-the centripetal acceleration =747.5*10^-17/1.1*10^-27=679.55*10^10 m/s^2

(g)&(h) the radius R=v^2/ac=460^2/679.55*10^10=31.14*10^-9 m
