Answer:
Ratio = 1:1
Explanation:
= initial momentum of the system
= final momentum of the system
For the momentum to be conserved , final total momentum must be equal to initial total momentum, so we have
Dividing both side by , we get
hence
Ratio = 1
Answer:
Force on the singly charged ion will be
Explanation:
We have given electric field E = 8 MN/C
So electric field in N/C will be
It is given that ion so charge on ion will be equal to
We have to find the electric force on the ion
Electric force is equal to , here q is charge and E is electric field
So force on the charge will be equal to
So force on the singly charged ion will be
