Answer:
The two small charged spheres are now 4.382 cm apart
Explanation:
Given;
distance between the two small charged sphere, r = 7.59 cm
The force on each of the charged sphere can be calculated by applying Coulomb's law;
where;
F is the force on each sphere
q₁ and q₂ are the charges of the spheres
r is the distance between the spheres
Therefore, the two small charged spheres are now 4.382 cm apart.
First you have to know the formula for work which is force times (x) distance which is equal to Newtons times (x) mass answer is in joules which is tge unit
Answer:
440J
Explanation:
First, let us find the <u>weight </u>of the barbell.
The formula to find the weight is :
W = m × g
Here,
m ⇒ mass ⇒ 20 kg
g ⇒ acceleration of gravity
<u>Let us find it now.</u>
W = m × g
W = 20 kg × 10 ms⁻²
W = 200N
And now let us find<u> the work done by this weight lifter.</u>
Work = Force × Displacement
<u>Let us find it now.</u>
Work = Force × Displacement
= 200N × 2.2m
=<u> 440J</u>
