If we put negative charge between two similar positive charges then what is it's equilibrium? And how?​
Gnesinka [82]

Your question has been heard loud and clear.

Well it depends on the magnitude of charges. Generally , when both positive charges have the same magnitude , their equilibrium point is towards the centre joining the two charges. But if magnitude of one positive charge is higher than the other , then the equilibrium point will be towards the charge having lesser magnitude.

Now , a negative charge is placed in between the two positive charges. So , if both positive charges have same magnitude , they both pull the negative charge towards each other with an equal force. Thus the equilibrium point will be where the negative charge is placed because , both forces are equal , and opposite , so they cancel out each other at the point where the negative charge is placed. However if they are of different magnitudes , then the equilibrium point will be shifted towards the positive charge having less magnitude.

Thank you

Francesca, who likes physics experiments, dangles her watch from a thin piece of string while the jetliner she is in takes off f
Tom [10]

Answer:

v_f = 82.3 m/s

Explanation:

When a suspended string makes and angle of 25 degree while aircraft is accelerating on runway then we can use force equations to find the acceleration of the aircraft

So we will have

T sin\theta = ma

T cos\theta = mg

now from above two equations we have

a = g tan\theta

a = (9.81) tan25

a = 4.57 m/s^2

now if it took 18 s to take off we can have final speed of the aircraft given by

v_f - v_i = at

v_f - 0 = (4.57)(18)

v_f = 82.3 m/s

SSSSS [86.1K]

Answer:

0.013N

Explanation:

F=\frac{mv^{2} }{r}

m=0.04, v=4.4m/s, r=60

F=0.013 N
