Explanation:
Given that,
Two particles, an electron and a proton, are initially at rest in a uniform electric field of magnitude 570 N/C.
We need to find their speeds after 47.6 ns.
For electron,
The electric force is given by :
Let a be the acceleration of the electron. So,
F = ma
m is mass of electron
Let v be the final velocity of the electron. So,
v = u +at
u = 0 (at rest)
So,
For proton,
Acceleration,
Now final velocity of the proton is given by :
Hence, this is the required solution.

Unlike fixed joints or cartilaginous joints, where the bones are connected by either connective tissue or cartilage, the bones in synovial joints are not directly joined by anything, which allows for a much greater range of motion.
