Calculating Electric Force Between Balloon & Denim

AI Thread Summary
To calculate the electric force between a charged balloon and denim, the formula Fe = k * q1 * q2 / r^2 is used, where k is the Coulomb constant, q1 is the charge of the balloon (-2.0 μC), q2 is the charge of the denim (assumed equal and opposite), and r is the distance between them (6.0 cm). Users are encouraged to show their calculations for accurate troubleshooting. The discussion highlights the importance of correctly applying the formula and units. Clarification on specific calculation errors is needed for further assistance.

Homework Statement



A balloon rubbed against denim gains a
charge of −2.0 μC.
The Coulomb constant is 8.98755 ×
109 N · m2/C2.
What is the electric force between the bal-
loon and the denim when the two are sepa-
rated by a distance of 6.0 cm? (Assume that
the charges are located at a point.)
Answer in units of N.

Homework Equations



q=n.e
Fe=kq1q2/r^2
e=Fe/q

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 'Collision of a bullet on a rod-string system: query'

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'

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...
