Answer:
Explanation:
mass of proton, m = 1.67 x 10^-27 kg
speed of proton, v = 350 km/s = 350,000 m/s
Momentum of proton, p = mass x speed
p = 1.67 x 10^-27 x 350000 = 5.845 x 10^-22 kg m /s
uncertainty in momentum, Δp = 0.1 % of p
Δp =
According to the principle
where, Δx be the uncertainty in position
Answer:
Explanation:
q1 = - 4.7 x 10^-9 C
q2 = - 9.7 x 10^-9 C
q3 = 7.2 x 10^-9 C
Potential at the centre of the circle, V = - 1900 V
Let the radius of the circle is r.
So, the potential is given by
r = 0.034 m = 3.4 cm
