As per the question,the current amplitude is given as i= -2.7 micro ampere
i.e -2.7 ×
as per the question the time is given as t=1.15s
we know that
hence q=i×t
hence the total charge passing through this point is given as
q= -2.7×× 1.15
= -3.105×
we know that q=ne where n is the number of electrons and e is the charge of electron
we have e= -1.602× coulomb
hence number of electrons n=
= 3.105××
=1.93820×
Answer:
D) 7500 N/m
Explanation:
Given :
Work done by the spring, W = 6 J
Stretch in the spring, x = 4 cm = 0.04 m
Consider k be the spring constant.
The relation between work done and stretch of the spring is:
Substitute the suitable values in the above equation.
k = 7500 N/m
