Answer:
speed of boat as
river speed is given as
Explanation:
When boat is moving down stream then in that case net resultant speed of the boat is given as
since the boat and river is in same direction so we will have
Now when boat moves upstream then in that case the net speed of the boat is opposite to the speed of the river
so here we have
as we know when boat is in downstream then in that case it covers 24 miles in 2 hours
also when it moves in upstream then it covers same distance in 3 hours of time
so we have speed of boat as
river speed is given as
Answer:
Explanation:
Given that
Length= 2L
Linear charge density=λ
Distance= d
K=1/(4πε)
The electric field at point P
So
Now by integrating above equation
