We have,
- The mass of sally's mug is 1 kg
- The pressure appliedby the mug is 1100 pascal.
We know that,
As, we already have the value of pressure, let's calculate that of force now;
- F = ma
- F = 1 × 9.8 { Acceleration due to gravity, let's round off it to 10}
- F = 10 N
Just put all the values in the formula now;
- P = F/A
- 1100 = 10 / A
- 1100/10 = A
- 110 m² = A
As, it is already mention that we need to find the radius of the mug, it is obviously a circular base.
We know that,
- Surface area = Circumference
So, let's solve it;
- Circumference = 2πr
- 110 = 2 × 22/7 × r
- 110 × 7/2 × 22 = r
- 5 × 7 = r
- 35 cm = r

Answer:
W = -0.480 J
Explanation:
given,
q₁ = 4 μC
q₂ = -4.10 μC
b = 0.381
k = 8.99 × 10⁹ Nm²/C²
![W = [-147.436\times (5.88-2.62)\times 10^{-3}]J](https://tex.z-dn.net/?f=W%20%3D%20%5B-147.436%5Ctimes%20%285.88-2.62%29%5Ctimes%2010%5E%7B-3%7D%5DJ)
W = -0.480 J
Work done by the electric force W = -0.480 J
The kilogram is the SI unit of mass and it is the almost universally used standard mass unit. The associated SI unit of force and weight is the Newton, with 1 kilogram weighing 9.8 Newtons under standard conditions on the Earth's surface.
