it is simple it would be frictional force only...
hope it helps
Answer:
a) Frictional Force
Explanation:
The answer will be only frictional force as :
★ For Gravitational Force, the gravity applies force on an body which pulls it downwards whether it is at rest or motion. Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.
★ For muscular force, the force is used when one body is moving and the second body may or may not be in motion. If the second body is in motion, then again the case of friction will come. It is a force that results because of the action of muscles and is a contact force since there is contact between the surfaces. Muscular force is required whenever the movement of the body occurs. Strolling, lifting, getting up from a seat, crossing a leg, and so on all require muscular force.
★ And for Buoyant Force, one body is at rest and the second gets inside the first where it experiences the force. Buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.
