Answer:
The number of turns in secondary coil is 4000
Explanation:
Given:
Current in primary coil 
A
Current in secondary coil 
A
Number of turns in primary coil 
In case of transformer the relation between current and number of turns is given by,
For finding number of turns in secondary coil,
Therefore, the number of turns in secondary coil is 4000
Force = -kx
80N=0.15m * -k
K=-80/0.15=533.333. Spring constant
Energy=1/2kx^2
1/2*(-80/0.15)*80^2=Energy
