Which one of the following is not a central force?

Which one of the following is not a central force?

Gravitationaal force of a point mass and electric force due to a point change. Examples of non-central force. Nuclear forces which hold the nucleons together in the nucleus and magnetic forces between two current carrying loops.

Is pseudo force electromagnetic in nature?

Solution : Pseudo force is not a real force. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. A block of mass 4 kg is suspended through two light spring balances A and B is series.

Does pseudo force exist?

A fictitious force (also called a pseudo force, d’Alembert force, or inertial force) is a force that appears to act on a mass whose motion is described using a non-inertial frame of reference, such as an accelerating or rotating reference frame. These apparent forces are examples of fictitious forces.

Is the Earth taller or wider?

The Earth is a bit wider than it is tall, giving it a slight bulge at the equator; this shape is known as an ellipsoid, or, more properly, a geoid. The Earth’s diameter at the equator is 7,926.28 miles, and its diameter at the poles is 7,899.80 miles.

Can flattening of Earth be explained by rotational motion?

Abstract: Flattening of earth’s Polar Regions and bulging of its equatorial region are usually attributed to ‘centrifugal force’ due to earth’s spin motion. ‘Centrifugal force’ is fictitious, yet it is assumed to physically affect earth’s shape.

How does centrifugal force affect the shape of the earth?

Rotation produces centrifugal force, which partially offsets the gravitational acceleration downward. So, the planet bulges a bit along the equator and is flattened a bit at the poles (where the surface spinning is slowest), which distorts the earth’s shape into a flattened oval.

What causes the slight flattening of Earth at the poles?

Answer. Answer:The Earth has poles which are flattened because of the centrifugal force that acts on its poles while it rotates. The rotating of the earth in the angles makes it also bulge at the equator.

Is the earth flattening?

Since the Earth is flattened at the poles and bulges at the Equator, geodesy represents the figure of the Earth as an oblate spheroid. The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.
