2. Two charges 160μC and -250μC are placed together at a distance of 150 centimeter apart. Find the force of attraction between each other. Also explain the nature of the force [Repulsing force = +ve, Attraction force = -ve]



Answers

Answer 1

The answer is -0.016 N, and as it negative, the nature of the force is attractive.

Finding the force of attraction

Coulomb's Law is given by :

[tex]\boxed {F = \frac{kq_{1}q_{2}}{r^{2}}}[/tex]

Solving

F = 9 × 10⁹ × 160 × 10⁻⁶ × -250 × 10⁻⁶ / (150 × 10⁻³)²F = -360000 × 10⁻³ / 22500 × 10⁻⁶F = -16 × 10⁻³F = -0.016 N

Answers

The issue with common source amplifier has been designed using a PMOS triode load is that:

It may detracts from voltage gotten due to the fact that it draws current.It is one that has a short life. It can be susceptible to overload of voltage

What is the problem(s) that might occur if a MOSFET's transconductance becomes large ?

Note that Transconductance is seen as a form of an expression that is regarding the performance of a bipolar transistor or what we call the field-effect transistor (FET).

In all, the larger the transconductance size for any device, the bigger or  greater the level of amplification and it is one that is said to be capable of sending, if all other factors are said to be in a constant state.

Note that Amplifier are said to be relatively linear and it also for bigger signal analysis.

Hence, The issue with common source amplifier has been designed using a PMOS triode load is that:

It may detracts from voltage gotten due to the fact that it draws current.It is one that has a short life. It can be susceptible to overload of voltage

if the mind drum diameter 6 m calculate how far the counterweight which is 10 tons will lift for each single rotation of the Drum Show all calculations​

Answers

Measure the diameter of the drum. This is the distance across a circular end. For instance, the diameter might measure 18 inches. Divide the diameter in half.

How to find single rotation of the Drum?

The diameter of the drum is : d=6m

We understand that in a winch there's a cable that's connected from the weight to be raised to the drum, around which it's is rolled. So the distance the counterweight is lifted coordinates to the circumference of the drum. The expression to calculate the counter weight lifted in every single rotation of the drum is provided by,

h lift =C = πd

Substituting the importance of d in the above expression .

C=227×6C=18.85m

Thus, the counter weight lifted in each circuit of drum is

18.85m.
