Answer:
(a) t = 1.1 x 10^-7 s
(b) 5.56 mm
(c) vx = 4.5 x 10^5 m/s, vy = 10^5 m/s
Explanation:
v = 4.5 x 10^5 m/s along horizontal direction
E = 9.60 x 10^3 N/C along vertical direction
(a) Let t be the time taken.
Horizontal distance, x = 5 cm = 0.05 m
Horizontal distance = horizontal velocity x time
0.05 = 4.5 x 10^5 x t
t = 1.1 x 10^-7 s
(b) Let the vertical displacement is y.
y = 1/2 a t^2
Here a be the acceleration.
a = force/ mass = q E / m = (1.6 x 10^-19 x 9.6 x 10^3) / (1.67 x 10^-27)
a = 9.19 x 10^11 m/s^2
So, y = 0.5 x 9.19 x 10^11 x (1.1 x 10^-7)^2 = 5.56 x 10^-3 m = 5.56 mm
(c) Let vx be horizontal component of velocity and vy be the vertical component of velocity after it travels for 5 cm horizontally.
vx is same as v because the acceleration in horizontal direction is zero.
vy = 0 + a t = 9.19 x 10^11 x 1.1 x 10^-7 = 10.109 x 10^4 m/s
vy = 1 x 10^5 m/s
Your answer is 45 because you would do 15*3 then that will get you 45
ISOTOPES (C) are atoms with the same number of protons, but different numbers of neutrons.

Answer:
Acceleration,
Explanation:
It is given that,
Speed of electron,
Charge on an electron,
Mass of electron,
Magnetic field,
Magnitude,
Magnetic force is given by :
Also, F = ma
So, the acceleration of the electron is . Hence, this is the required solution.
A day is 24 hours so you divide the distance in a day by the number of hours in a day.
25,992/24=1083.
Answer: 1083 mph
