As the Earth doesn't care how massive an object is when one leaves two bodies with different masses they fall with the same g=9.81
meter/second.second.
so is with a pendulum as they release from their maximum height ,they won't become affected by their masses.
But if you connect some mass...
what you need is a sum of two fields:
first field due to the straight wire and this field is perpendicular out of the page towards your eye which is your second term (mu,zero).I/2.pi.R.
the field due to loop which is your first term
that is (mu ,zero).I/2R.
This second field is again...
