Answer:
2.24 m/s²
Explanation:
Using equation of motion
s = ut + at²
u = 0 , t = 3.17 s , s = 11.26 m
Put these values in the equation above
11.26 = 0 +.5 x a( 3.17)²
a = 2.24 ms⁻².
So acceleration due to gravity on that planet will be 2.24 m s⁻².
Answer:
Their kinetic energy will increase but potential energy will decrease.
Explanation:
Given that
Initial velocities of electron and proton is zero.
We know that ,electron have negative charge and proton have positive charge it means that they will attract to each other.We know that opposite charge attract to each other and same charge repels to each other.
It means that the velocities of proton and electron will increase and that leads to increase in the kinetic energy of proton and electron.
We know that potential energy U
So when r will decrease then U will increase but in negative direction it means that U will decrease.
So we can say that their kinetic energy will increase but potential energy will decrease.
