Answer:
Explanation:
Given
charge is placed at 
another charge of 
is at 
We know that Electric field due to positive charge is away from it and Electric field due to negative charge is towards it.
so net electric field is zero somewhere beyond negatively charged particle
Electric Field due to 
at some distance r from it
Now Electric Field due to 
is
Now 
thus 
Thus Electric field is zero at some distance r=1.43 cm right of
This is a very very difficult one for me, let me get back to you with the proper answer.
Answer:
I think D is correct
Explanation:
C is decreasing function, probably worst
A is arctan -> in radian, the rate of increasing is very slow-> second worst
B(14) = ln(9*14) = 4.8
D(14) = sqrt(8+14^2)=14.2
Answer:
Explanation:
The phenomenon can be modelled after the Bernoulli's Principle, in which the sum of heads related to pressure and kinetic energy on ground level is equal to the head related to gravity.
The velocity of water delivered by the fire hose is:
The maximum height is cleared in the Bernoulli's equation:
