Yes, it’s a uniform 3 KN/m
And the diagram doesn’t give the angle between the bridge and the wall, so I don’t know if it’s possible to calculate the resulting force
This is my attemp of solution:
Since the formula to calculate the tension is T=mg
I first calcualted the weight of the bridge with the ecuation
W= mg m=W/g
m= 18,000 N / 9.81 m/s
m= 1834 kg
So T=(1834)(9.81)= 17,991 N
But this seems no logical to me because the Tension force is a bit less...
Is this formula:
E=((1)/(4(3.1416)(8.85X10^-12)) ((q)/(r)^2)
But what is the formula to calculate the q, the charge given the E (electric field) and r (distance)
1. The problem is: Which charge will a sphere have if it has a diameter of 0.26 meters and produces an electric field of 1030 N/C in the surface? 2. Gauss Law3. I need the charge of the sphere but i couldn´t find any formula to calculate the charge given the distance (r) and electric field (E)
