Two 1.9 kg masses are 1.1 m apart (center to center) on a frictionless table. Each has + 9.6 μC of charge.

Anni [7]

Answer:

F= 0.6 N

Explanation:

Fe(electrical force)= $k q1q2/r^2$

$k=9*10^9\\q1=-9.6 *10^-6 C\\q2= -9.6*10^-6 C\\r= 1.1m$

So,

$F=\frac{9*10^9*-9.6 *10^-6 C* -9.6*10^-6 C}{1.1^2}$

$F= 0.6 N$

What material parameters determine resistivity?

sleet_krkn [62]

Answer:

Resistivity $\rho =\frac{RA}{l}$

It depends upon cross sectional area and length of material

Explanation:

The resistance of any material is given by $R=\frac{\rho l}{A}$ , here $\rho$ is the resistivity of material , l is length of material and A is cross sectional area

So resistivity $\rho =\frac{RA}{l}$

So resistuivity of any material depends upon area of cross section and length of material

If cross sectional area will be more then resistivity will be more. And is length of the material will be more then resistivity will be less
