Homework Statement


A helium nucleus ( 2 protons and 1 neutron stripped of its electrons is 0.03 mass from a single proton. What is the direction and amount of the acceleration of the proton?

Homework Equations


acceleration= force net/ mass
force= Kq1 xKq2 / r^2
K is constant
q1 is the charge of one object
q2 is the charge of another object
r is the distance between the centers of each charged mass

The Attempt at a Solution


My guess is charge of 2 protons is q1 and charge of 1 neutron is q2.
Can somebody help me with this problem?

Sorry, but the problem statement contains some typos and is hard for me to follow. Could you please try again, and include any figure that comes with the problem? You can Upload PDF and JPEG images using the UPLOAD button in the lower right of the edit window. Thanks. :smile:
 
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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
