Answer:
3.62 m and - 1.4 m
Explanation:
Consider a location towards the positive side of x-axis beyond the location of charge Q₂
x = distance of the location from charge Q₂
d = distance between the two charges = 2 m
For the electric field to be zero at the location
E₁ = Electric field by charge Q₁ at the location = E₂ = Electric field by charge Q₂ at the location


x = 1.62 m
So location is 2 + 1.62 = 3.62 m
Consider a location towards the negative side of x-axis beyond the location of charge Q₁
x = distance of the location from charge Q₁
d = distance between the two charges = 2 m
For the electric field to be zero at the location
E₁ = Electric field by charge Q₁ at the location = E₂ = Electric field by charge Q₂ at the location


x = - 1.4 m
Answer:
Explanation:
Using equations of motion:
(a)
v=u+at
∴0=19.4−8.57t
∴t=19.4/8.57
=2.3s
B. Using s= ut + 1/2 at²
19.4(2.3)-1/28.57(2.3)²
= 21.92rad
So, all Turkeys work to attract female Turkeys, but only dominant Turkeys benefit from it, and the less dominant Turkeys don't benefit at all from it. That means that they are exhibiting altruism:selfless behavior.
However, in practical terms their behaviour also helps them, as they are often related to the dominant males.
Answer:
10,000 eV
Explanation:
Due to the law of conservation of energy, the kinetic energy of the electron at the end of its path is equal to its initial electric potential energy, given by:

where
q is the electron charge
is the potential difference
Here we have:
is the electron's charged
is the potential difference
Substituting into the formula, we have
