Answer:

Force between two equal charges will be 608.4 N

Explanation:

We have given charges q_1=0.65C\ and\ q_2=0.65C

Distance between the charges = 2.5 km = 2500 m

According to coulombs law force between two charges is given by

F=\frac{1}{4\pi \varepsilon _0}\frac{q_1q_2}{r^2}=\frac{Kq_1q_2}{r^2}, here K is constant which value is 9\times 10^9Nm^2/C^2

So force F=\frac{9\times 10^9\times 0.65\times 0.65}{2500^2}=608.4N

A pulley has an initial angular speed of 12.5 rad/s and a constant angular acceleration of 3.41 rad/s2. Through what angle does
Novosadov [1.4K]

Answer:

Angle turn pulley is 113 rad

Explanation:

given data

angular speed w = 12.5 rad/s

angular acceleration a 3.41 rad/s²

time t = 5.26 s

to find out

what angle does the pulley turn

solution

we get here angle by this equation that is here

angle  turn = w × t + 0.5 × a × t²     ......................1

put here value we get

angle  turn = w × t + 0.5 × a × t²

angle  turn = 12.5 × 5.26 + 0.5 × 3.41 × 5.26²

Angle turn =  65.75 + 47.17

Angle turn = 112.92 rad = 113 rad
