Explanation:
The given data is as follows.
Electric field (E) =
Charge (e) = C
Formula to calculate the magnitude of force is as follows.
F = qE
=
=
Therefore, we can conclude that magnitude of the force on a calcium ion with charge +e is .
Answer:
option B
Explanation:
Current unit is ampere (A)
Ampere will be equivalent to = ?
we know,
Current can be define as the charge per unit time
unit of charge(Q) is coulomb which is equal to C.
unit of time(t) is equal to 's'.
now,
unit of I = C/s
ampere(A) is equivalent to C/s
The correct answer is option B
