How Do You Calculate the Electrical Charge of a Particle?

AI Thread Summary
To calculate the electrical charge of a particle, the relevant formula involves the relationship between electrical potential energy, electric field strength, and charge. For a particle moving through an electric field, the change in electrical potential energy (ΔU) can be expressed as ΔU = q * ΔV, where q is the charge and ΔV is the potential difference. The potential difference can also be calculated using the electric field strength (E) and distance (d) with the formula ΔV = E * d. In the given problem, the charge can be determined by rearranging the formulas based on the provided values. Understanding these relationships is crucial for solving the problems presented.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
