Finding Force of an electron in motion

AI Thread Summary
To find the force exerted on an electron accelerating from 3.24x10^5 m/s to 6.93x10^5 m/s over a distance of 5.15 cm, one must first calculate the acceleration using the kinematic equations. Once the acceleration is determined, the force can be calculated using Newton's second law, F = ma, where 'm' is the mass of the electron. The comparison of this force with the weight of the electron, which is typically negligible due to its small mass, highlights the significant impact of acceleration in this scenario. Participants are encouraged to share their calculations for further assistance. Accurate calculations are crucial for understanding the dynamics of the electron's motion.

Please help, I keep getting the wrong answer but do not know why. Thanks An electron of mass 9.11x10^(-31) kg has an initial speed of 3.24x10^5 m/s. It travels in a straight line, and its speed increases to 6.93x10^5 m/s in a distance of 5.15 cm. Assume its acceleration is constant.

a. determine the force exerted on the electron.

b. compare this force with the weight of the electron, which we neglected.

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'

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...
