Explanation:
velocity of disc
lets call (h) 1 m to make it simple.
= 3.614 m/s
m/s pointing towards this:
velocity of hoop=
lets call (h) 1m to make it simple again.
m/s
The disc is the fastest.
While i'm on this subject i'll show you this:
Solid ball
solid disc
hoop
The above is simplified from linear KE + rotational KE, the radius or mass makes no difference to the above formula.
The solid ball will be the faster of the 3, like above i'll show you.
solid ball: velocity
let (h) be 1m again to compare.
m/s
solid disk speed
uniform hoop speed
solid sphere speed
Answer:
(a). The change in the protons electric potential is 0.639 kV.
(b). The change in the potential energy of the proton is
(c). The work done on the proton is .
Explanation:
Given that,
Speed
Initial potential V=100 V
Final potential = 150 V
(a). We need to calculate the change in the protons electric potential
Potential energy of the proton is
Using conservation of energy
Put the value into the formula
(b). We need to calculate the change in the potential energy of the proton
Using formula of potential energy
Put the value into the formula
(c). We need to calculate the work done on the proton
Using formula of work done
Hence, (a). The change in the protons electric potential is 0.639 kV.
(b). The change in the potential energy of the proton is
(c). The work done on the proton is .
