Question

In the given diagram, a line of force of a particular force field is shown. Out of the following options, it can never represent.
A. an electrostatic field
B. a magnetostatic field
C. a gravitational field of a mass at rest
D. an induced electric field

Answer 1

Hint: Electrostatic field and attraction field's lines start from a point and end at some other point. Yet, not an attractive field, additionally prompted electric field likewise acts as an attractive field.

Complete answer:
By mass-energy comparability, the attraction field has a relativistic mass thickness extending to its energy thickness. I look to all the more likely comprehend this mass of the gravitational field by finding out if it plays three customs. Parts of mass: the function in the protection of mass the inertial job and the as a hotspot for attraction.
An electrostatic field exists in the locale encompassing an electrically charged item. This charged item, when acquired close to an uncharged particle, can prompt a charge on some time ago nonpartisan item. This is known as a prompted charge. Quantitatively, this actuated charge is the voltage inclination between two focuses at various possibilities. Much of the time, it is the electric field from the charge which causes electrostatic impacts.
One procedure for assessing the conceivable starting risk is in this way to gauge the electric field power $ \left( {\dfrac{m}{v}} \right) $ at the outside of the charged texture. It has been shown that field powers not exactly $ 5{\text{ }}kVc{m^{ - 1}} $ can't touch off any fuel that has a base start energy more noteworthy than $ 0.15{\text{ }}mJ $ .

Hence the correct answer is an option (A), (B).

Note:
A mass very still has a field that is appealing in nature, i.e., a straight line towards the focal point of the mass. Essentially, an electric field is likewise a straight line emerging from a positive charge and coming into a negative charge.
