2 equal charges, 27 micro Coulomb each, are separated by 5 cm. Find force between those.
padilas [110]

Answer:

The force between charges is  F= 2.624*10^3N.

Explanation:

The Coulomb force F between the two charges q_1 and q_2 separated by distance d is given by the equation

F = k\dfrac{q_1q_2}{d^2}

where k is the coulombs constant, and has the value

k= 9*10^9N\cdot C\cdot m^2.

Now in our case

q_1=q_2=27\mu C =27*10^{-6}C

and

d= 5cm =0.05m,

therefore, the Coulomb force between the charges is

F =( 9*10^9N\cdot C\cdot m^2)*\dfrac{(27*10^{-6}C)(27*10^{-6}C)}{(0.05m)^2}

\boxed{ F= 2.624*10^3N}

A 3.00-m rod is pivoted about its left end. A force of 7.80 N is applied perpendicular to the rod at a distance of 1.60 m from t
dalvyx [7]

Answer:

The net torque about the pivot is and the answer is 'c'

c. T_{net}=8.58

Explanation:

T=F*d

The torque is the force apply in a distance so it is the moment so depends on the way to be put it the signs so:

T_1=F_1*d_1

T_1=7.8N*1.6m=12.48N*m

T_2=F_2*d_2

T_2=2.60N**cos(30)*3.0m

T_2= - 3.9 N*m

Now to find the net Torque is the summation of both torques

T_{net}=T_1+T_2

T_{net}=12.48N-3.9N=8.58N
