Working displayed in the picture below, the answer is -11 m s^-2
Kinetic energy would increase sir.
Answer:
303.15K
Explanation:
the formula for converting celsius into kelvin is adding 273.15 to the number
If one of two interacting charges is doubled, the force between the charges will double.
Explanation:
The force between two charges is given by Coulomb's law

K=constant= 9 x 10⁹ N m²/C²
q1= charge on first particle
q2= charge on second particle
r= distance between the two charges
Now if the first charge is doubled,
we get 
F'= 2 F
Thus the force gets doubled.
