Efficiency of heat engine is determined by the ratio of difference in temperature of cold from hot reservoir to the temperature of hot reservoir over temperature of hot reservoir.
Answer:
q2 = - 8 ×
C
negative sign because attract together
Explanation:
given data
q1 = +3.2 µC = 3.2 ×
C
distance r = 0.28 m
force F = 2.9 N
to find out
q2 (magnitude and sign)
solution
we know that here if 2 charge is unlike charge
than there will be electrostatic force of attraction , between them
now we apply coulomb law that is
F =
............1
here we know
= 9 ×
Nm²/C²
so from equation 1
2.9 = 9 ×
×
q2 = 
q2 = - 8 ×
C
