Answer:
Q = 29.4 x 10⁻⁹ C. 
Step-by-step explanation:
Electric field due to a charge Q at distance d is given by coulomb law as follows 
Electric field 
E = k Q /d² 
where for air k which is a constant is 9 x 10⁹ 

Given E = 32.08 , d = 2.84 m 
Putting these values in the relation above, we have 
![[tex]32.08=(9* 10^9* Q)/((2.84)^2)](https://img.qammunity.org/2020/formulas/physics/college/j00985f3o7eapkfsqqpftbsg3dvos489eo.png) [/tex]

Q = 29.4 x 10⁻⁹ C.
