Ответ:
acceleration = Force/mass
If you double the mass then acceleration will be halved in order for the equation to still equal.
New acceleration = Force/(2)mass
New acceleration = (1/2)* Force/mass>if you compare this to original acceleration equation above it is 1/2

Explanation:
The total charge in the disks
must be conserved before and after bringing them together.
Lets equate the sum of the initial charge with the sum of the final for the disk:
So, the initial charges must sum +17 μC.
Now, as there are no charges over +17 μC, this means that both charges must be positive.
As the only positive charges are
and 
, this disk must be the ones we are looking for. And, as we can see, they sum 17 μC:
