We have that for the Question,it can be said that the field has a <u>value </u>of
From the question we are told
a small object with a charge of magnitude q creates an electric field. at a point 1.0 m to the north of the charge the field has a value of 2.0 n/c directed south. at a <em>point </em>0.5 m to the west of the <em>charge </em>the field has a value of

Answer:
44 1/3 cm
Explanation:
The cube has an edge length of ∛0.027 m = 0.3 m, so a center of mass (CoM) 15 cm above the floor.
The sphere's center of mass is 40 cm above the top of the cube, so is 70 cm above the floor. The weighted average of the CoM locations is ...
((15 cm)(0.700 kg) +(70 cm)(0.800 kg))/(0.700 kg +0.800 kg)
= (10.5 kg·cm +56 kg·cm)/(1.500 kg) = 44.333... cm
The center of mass of the two-object system is 44 1/3 cm above the floor.

<em>Comment on the units</em>
We're not familiar with "hcm" as a unit. We presume that you can convert the given answer to the units you desire.
Explanation:
The junction rule says that the sum of the currents going into a junction must equal the sum of the currents leaving a junction. This describes the conservation of current.
