Question

the magnitude of the electric field at a point in space does not depend upon
1)the distance from the charge causing the field
2)the sign of the charge causing the field
3)the magnitude of the charge causing the field
4)medium in which charges are kept
​

Answer 1

Answer: 2)the sign of the charge causing the field.

Explanation:

• We need to know the factors which affect the electric field.
• We know the formulae of electric field is

                     E=$\frac{1}{4\pi \alpha } \frac{q_{1}q_{2} }{r^{2} }$

           Here, The electric field is affected by the magnitude of charge, distance from the charge causing the field and the medium in which it is kept.

It does not depend upon the sign of the charge.

• Hence, the correct answer is the sign of the charge causing the field.

Answer 2

2)the sign of the charge causing the field is the solution.

Explanation:

• The electric-powered area formulation offers the electrical area significance at a sure factor from the fee Q, and it relies upon on factors: the quantity of fee on the supply Q and the distance r from the factor to the supply Q.
• An electric-powered asset is related to every factor in the area whilst the fee is found in any form.
• The significance and route of the electrical area are expressed through the cost of E, referred to as electric-powered area energy or electric-powered area intensity, or surely the electrical area.
• The electric-powered area is suffering from the significance of charge, distance from the charge inflicting the sector, and the medium wherein its miles are kept.
• It does now no longer depend on the signal of the charge.

Hence, the ideal solution is the sign of the charge causing the sector.
