Question

Muscular Force is a type of
A.) Gravitational force
B.) Contact force
C.) Non contact force
D.) Frictional force

Answer 1

Hint: Muscular forces are the forces which utilize muscle power and this requires pushing, pulling, holding, etc. a body.

Complete Step By Step Solution:

Contact forces require contact with a body, for the force to be applied on the body. Non contact forces are the forces which can be applied on a body without physically touching the body.
Almost all of our daily activities like kicking a ball, holding a book, walking, eating everything require muscular forces for their execution. All these activities require contact with another body. Thus muscular forces are contact forces.
Hence the correct option is B.

Additional Information:
Frictional force is also a contact force. It is exerted when two bodies in contact slide against one another i.e. if they have different velocities. Gravitational force is a non contact force. It is exerted between any two objects having mass irrespective of their position, shape, size, nature etc. It is a proportional two product of masses of the two objects and inversely proportional to square of distance between them. It’s the same force which binds us with the earth. It in fact binds the universe together.

Note: All the muscular forces are electromagnetic in nature. This means at an atomic level these forces are produced due to changes in electric and magnetic fields. So, if one of the options was electromagnetic, it would have been the correct one too.
