oops one on table, one hanging

no m3... 2. yes

Homework Statement A block of mass1 5.0 kg is on a table that bonds a coefficient of friction of 3.00. Mass1 is attached to Mass2 by a string, and Mass2 is hanging over the table. The system is released from rest for it to accelerate. Homework Equations F=ma F fric = μFnormal The...

Homework Statement So basically there are two parallel wires the wire on the left has an increasing current going north. What would be the direction of the current in the wire left of it? Homework Equations Right Hand Rules The Attempt at a Solution So I'm really not...

thank you so much!

how do i know which voltage comes first in the difference?

Homework Statement A 4.0μC charge is situated at the origin of an xy coordinate system. What is the potential difference between the points x=4.0m and y=2.0m because of this charge? Homework Equations V = k X q/r The Attempt at a Solution So i got the absolute value of the...

so its not zero right?

Homework Statement Two equal point charges of magnitude 4.0 μC are situated along the x-axis at x1=-2.0m and x2= 2.0m. What is the electric potential at the origin of the xy coordinate system? Homework Equations ΔV= Kc (q/r) The Attempt at a Solution Do voltages cancel each...

really 385 views and no response...?

Homework Statement By what method will a positively charged rod produce a negative charge on a conducting sphere that is placed on an insulating surface. Homework Equations a) by means of conduction b) by means of induction c) by means of convection d) none of the choice are correct...

Homework Statement Two point charges of +30μC and -9μC are separated by a distance of 20.0 cm. What is the intensity of electric field E midway between these two charges? Homework Equations force electric= kQq/ r^2 Electric field= force elctric /q = k X Q / r^2 The Attempt at a...

Is the balloon and denim at first neutral? Then I guess the balloon would have a -8microC and the denim a +8microC. If this is correct, then I know how to solve this problem. Thank you for making my brain actively think!

The denim.

Question: A baloon rubbed aginst denim gains a charge of -8microC. What is the electric force between the balloon and the denim when the two are separated by a distance of 5.0 cm? (Assume that the charges are located at a point.) Equations used: F electric = K q1 X q 2 / r^2 Steps...
