It is the same, there is no difference.
In fact, the force of gravity on an object is equal to the weight of the object, defined as
where m is the mass of the object and g=9.81 m/s^2 is the acceleration of gravity, As we can see, the magnitude of this force depends only on the mass of the object: in this problem, both the objects (the piece of iron and the piece of glass) have same mass (1 kg), therefore they have same weight, and same force of gravity.
Answer:
The amount of charge at the center is -132.7 nC
Solution:
As per the question:
Electric flux from one face of cube,
Edge, a = 19cm
Since, a cube has six faces, thus total flux from all the 6 faces =
Also, from Gauss' law:
A. The switch within the closed circuit is opened.
If the switch is opened current will stop flowing, as the current will meet a gap, that is not connected by a conductor.
Answer:
5.6875 × 10^(10) electrons
Explanation:
To some this we will use the formula;
q = ne
Where;
q is charge
n is number of electrons
e is electron charge = 1.6 × 10^(-19) C
We are given q = -9.10 nc
1 nc = 10^(-9) C
Thus;
q = -9.1 × 10^(-9) C
Since q is negative, then e = -1.6 × 10^(-19) C
Thus;
-9.1 × 10^(-9) = n(-1.6 × 10^(-19))
n = -(9.1 × 10^(-9))/(-1.6 × 10^(-19))
n = 56875000000 electrons = 5.6875 × 10^(10) electrons
