Answer:
The maximum electrical force is
.
Explanation:
Given that,
Speed of cyclotron = 1200 km/s
Initially the two protons are having kinetic energy given by

When they come to the closest distance the total kinetic energy is converts into potential energy given by
Using conservation of energy


Put the value into the formula


We need to calculate the maximum electrical force
Using formula of force



Hence, The maximum electrical force is
.
Answer:
λ = 470.66 nm
Explanation:
for bright fringe
D= distance between slit and screen
d= distance between the slits
for first order bright fringe m = 1,


for dark fringe,we have
Now to get the dark fringes at the same location we should have;
(706)D/d = (m + 1/2)λD/d
put m = 1
(1 + 1/2)λ = (706)
λ = 470.66 nm
Length•Width•Height is the answer
Answer:
according to this question best answer is C
