Thomson experiment he calculated the charge to mass ratio just be passing the fundamental charge through a tube
He calculated the charge to mass ratio just by finding the deflection of charge while it is passing through the constant electric field
so here we will use the deflection as following
let say it passes the field of length "L"
so here we have
now in the same time if it deflect by some distance
now by solving this equation we can find e/m ratio
so here correct answer will be
the electron's charge-to-mass ratio
Answer:
a)11,71 m/s
b)12.73 m/s
Explanation:
We apply the conservation principle because there is no friction between the hill and the sled:
Total initial energy (Ei) = Total initial energy (Ef), Equation(1)
We define:
K = Kinetic energy =
U = Potential energy =
m = mass (kg)
v = velocity (m/s)
h = height (m)
g = gravity acceleration =
A) hi=7m, hf=0 ,vi=0 , vf=?
Answer: She reaches the base of the hill with speed of 11.22 m/s
B) hi=7 m, vi=5 m/s, hf=0, vf=?
We divide all terms by m
Answer: She will move with a speed of 12.73 m/s when she reaches the base of the hill
Answer:
-1161.29 V/m
