force between two parallel wire is
f/l = mueo*i1i2/2pir
f/l = 2*10^-7*i1i2/rl
i2 = f*r/2*10^-7*i1
i2 = 342.9 A
The new electrostatic force will be 384 units.
The electrostatic force of attraction between two charges (charge of object 1) and (charge of object 2) separated by a distance d is given by
is the permittivity of free space.
Initially, we have,
Now, if the charge of object 1 is multiplied by 1, the charge of object 2 is multiplied by 3, and the distance separating objects 1 and 2 is divided by 4, we have, .
The new electrostatic force will be,
units.
We have,
Hence,
Hence, the new electrostatic force will be 384 units.

The current is defined as the amount of charge Q that passes through a certain point of a wire in a time
:
But the charge Q flowing in the wire is just the charge of a single electron, e, times the number of electrons N:
so the current can be rewritten as
Using
,
(charge of one electron), and
, we find the current:
Therefore correct answer is A).
Earth<span> and the other three </span>inner<span> planets of our solar system (</span>Mercury<span>, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum.
