P.E=0.0675 J
Explanation:
Elastic potential Energy=Force × distance of displacement
The formula to apply is;
P.E=1/2 ks²
where k is the spring constant given as; 1.5 *10^-2 N/m and s is the displacement
In this case,
s=3
P.E= 1/2 * 1.5 × 10^-2 ×3²
P.E=1.5×10^-2*4.5
P.E=0.0675 J

Answer: option 4: A wire that is 2-mm thick and coiled.
Explanation:
The current in each wire is same. The magnetic field due to a current carrying wire increases if the wire is coiled with the more number of turns. A thick wire would cause low resistance to the current. Hence, a 2-mm thick wire which is coiled would produce the strongest magnetic field.
