Answer:
A
Explanation:
Contact force A contact force is any force that requires contact to occur. ... Contact forces are often decomposed into orthogonal components, one perpendicular to the surface (s) in contact called the normal force, and one parallel to the surface (s) in contact, called the friction force. In the Standard Model of modern physics, the four fundamental forces of nature are known to be non-contact forces.

Answer:
Current = 32.6 A
Explanation:
Magnetic field = B = 0.160 T
No. of turns of coil = N = 4300
Length of the solenoid = L = 1.10 m
Current required depends on the B, L , N and the magnetic permeability μ₀
B = μ₀ N I / L
⇒ Current = I = B L / μ₀N = ( 0.160 ) ( 1.10) / (4π × 10⁻⁷)(4300)
= 32.6 A
