Answer:
N
Explanation:
We are given that three charged particle are placed at each corner of equilateral triangle.
Side of equilateral triangle =3.3 cm=
We know that each angle of equilateral angle=
Net force=F =
Where k=
If we bisect the angle at then we have 30 degrees from there to either charge.
Direction of vertical force due to charge and
Therefore, force will be added
Vertical force=
Vertical net force=
Vertical force =
Vertical force= (towards
Horizontal component are opposite in direction then will b subtracted
Horizontal force=
Horizontal force= N(towards
Net electric force acting on particle 3 due to particle =
Net force=
Net force= N
The astronaut's mass doesn't change. It's the same wherever he goes,
because it doesn't depend on what else is around him.
His weight depends on what else is near him, so it changes, depending
on where he is.
Weight = (mass) x (gravity)
On Earth, Weight = (145 kg) x (9.81 m/s²) = 1,422.5 newtons.
(about 320 pounds)
On the moon, Weight = (145 kg) x (1.62 m/s²) = 234.9 newtons.
(about 53 pounds)
Frequency has the unit hertz.
Friction- the external force that acts on objects and causes them to slow down when no other external force acts upon them.
