The correct answer is
B. Interference
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
Answer:
e) half
Explanation:
as we know relation b/w charge(Q) , capacitance (C) and voltage (V) is
Q = CV ...........(i)
we also know capacitance of a capacitor for separation d and area A is
C = ∈₀A/d ...........(ii)
from the above equation it is clear that C is inversely proportional to separation if separation doubled capacitance will reduced to half and from equation first charge is directly proportional to capacitance.
that s why magnitude of charge will reduced to half
so option (e) is right answer
