Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers

Answer:
655128 ohm
Explanation:
C = Capacitance of the capacitor = 7.8 x 10⁻⁶ F  
V₀ = Voltage of the battery = 9 Volts  
V = Potential difference across the battery after time "t" = 4.20 Volts  
t = time interval = 3.21 sec  
T = Time constant
R = resistance  
Potential difference across the battery after time "t" is given as  
 
 
T = 5.11 sec  
Time constant is given as  
T = RC  
5.11 = (7.8 x 10⁻⁶) R  
R = 655128 ohm
