Answer: The speed necessary for the electron to have this energy is 466462 m/s
Explanation:
Kinetic energy is the energy posessed by an object by virtue of its motion.
K.E= kinetic energy =
m= mass of an electron =
v= velocity of object = ?
Putting in the values in the equation:
The speed necessary for the electron to have this energy is 466462 m/s
To solve this problem, we will apply the concepts related to the linear deformation of a body given by the relationship between the load applied over a given length, acting by the corresponding area unit and the modulus of elasticity. The mathematical representation of this is given as:
Where,
P = Axial Load
l = Gage length
A = Cross-sectional Area
E = Modulus of Elasticity
Our values are given as,
l = 3.5m
D = 0.028m
E = 200GPa
Replacing we have,
Therefore the change in length is 1.93mm
Explanation:
It is given that,
Radius of circular particle accelerator, r = 1 m
The distance covered by the particle is equal to the circumference of the circular path, d = 2πr
d = 2π × 1 m
(a) The speed of satellite is given by total distance divided by total time taken as :
Let t is the period of the particle.
d = distance covered
s = speed of particle
It is given that the charged particle is moving nearly with the speed of light
(b) On the circular path, the centripetal acceleration is given by :
Hence, this is the required solution.
