Answer:
 q = 4.5 nC 
Explanation:
given,
electric field of small charged object, E = 180000 N/C
distance between them, r = 1.5 cm = 0.015 m
using equation of electric field

k = 9 x 10⁹ N.m²/C²
q is the charge of the object

now,

       q = 4.5 x 10⁻⁹ C 
       q = 4.5 nC 
 the charge on the object is equal to 4.5 nC
 
        
                    
             
        
        
        
As the speed increases and the pressure decreases
