I believe the correct answer would be they join north pole to south pole. The direction of these lines always goes from the direction of north to south pole. These lines forms loops in order to favor the way which requires or has less resistance. Hope this helps.

Magnetic field lines are presentation of magnetic field on paper

There is no real existence of magnetic field lines in the surrounding of a magnetic material but it is an hypothetical way to represent the magnetic field variation.

There are several rules to draw the field lines on paper which are as following

1. magnetic field lines start from north pole and ends at south pole

2. density of field lines shows the strength of magnetic field

3. tangent to the magnetic field line represents the direction of magnetic field so there can not exist a point where two magnetic field lines will intersect

so as per all above rules the correct answer should be

<em></em>

<em>A. They join north pole to south pole. </em>

Which is usually greater for a pair of surfaces, the coefficient of static friction or the coefficient of sliding friction? why
lorasvet [3.4K]

Explanation :

Static friction is the frictional force between two objects that are at rest. While sliding friction is the frictional force between two objects in contact and are sliding w.r.t each other.

Static friction is usually greater than sliding friction because in static friction the contact forces is more and the interlocking between objects is tight as compared to sliding friction.

Ans of this question A test charge of 1 couloumb moved from 30cm against the field of intensity 50N/c find the energy store in i
UkoKoshka [18]

Answer:

A. Zero

Explanation:

Given data,

The charge of the test charge, q = 1 C

The distance the charge moved against the filed of intensity, x = 30 cm

                                                                                                        = 0.3 m

The electric field intensity, E = 50 N/C

The energy stored in the charge at 0.3 m is given by the formula,

                                V = k q/r

Where,                        

                                     = 9 x 10⁹ Nm²C⁻²

The charge is moved from the potential V₁ to V₂ at 30 cm

Substituting the given values in the above equation

                            V₁ = 9 x 10⁹ x 30 / 0.3

                                =  1.5 x 10¹² J

And,

                            V₂ = 1.5 x 10¹² J

The energy stored in it is,

                             W = V₂ - V₁

                                  = 0

Hence, the energy stored in the charge is, W = 0
