Answer:
132.64m/s
Explanation:
Averagevelocity= distance/time
From the question, the distance d = 825m
time t = 6.22 secs
Using the above formula
We have
average velocity = 825/6.22
= 132.64m/s
8.34 m/s

Answer:
0.2 m
Explanation:
magnetic force = centripetal force
qvB = mv² / r
cancel v on both side and make r subject of the formula
r₁ = mv / qB where m = mass of ion, v = velocity of the ion
r₁ = ( 235 × 1.67 × 10⁻²⁶ × 2.81 × 10⁵) / ( 1.6 × 10⁻¹⁹ × 0.605 T) = 1139.24 × 10⁻² = 11.4 m
r₂ = ( 238 × 1.67 × 10⁻²⁶ × 2.81 × 10⁵) / ( 1.6 × 10⁻¹⁹ × 0.605 T) = 1153.78 × 10⁻² = 11.5 m
D, distance between the impact points formed = d₂ - d₁ where d₂ and d₁ represent the diameters of the charged ions
D = (2 × 11.5 m) - ( 2 × 11.4) = 2 ( 11.5 - 11.4) = 0.2 m
