Question

A scientist fixes a test charge q¹ to point P and then measures the electrostatic force it experiences there. She then calculates the magnitude of the electric field by applying the equation E=F¹/ q¹. –Which change to her procedure would vary the value of E = F¹/ q¹, which change to her procedure would vary the value of E that she calculates?

Answer 1

(1)Electric field depends on the source (or)static charge (2,). Electric flux at a point (r) due to source chatge (Q,)is, From Gauss law.flux through the closed surface is, From the above two equations Imagine a test charge(a1) at the point (r) from Qs,coloumb force between Q, and g is C1 Electric field at a point (r) is defined as the force experi enced by a unit positive charge imagined at the point From (1)and (2). electric field depends on [Eoe]E in or der to cal culate variati on of electric field scienti sts vary magnitude a source charges |& distance from source to imagined point
