Answer:
Total distance does the grasshopper travel before the cars hit is 150 m
Explanation:
Each car moves x=100 m before they collide. Both the cars moving in constant velocity. time taken t by each car is
where x is the distance traveled with velocity v
The insect is moving through this time period with a constant velocity of 15 m/s
The distance traveled by grasshopper is
Answer:
The total charge on the rod is 47.8 nC.
Explanation:
Given that,
Charge = 5.0 nC
Length of glass rod= 10 cm
Force = 840 μN
Distance = 4.0 cm
The electric field intensity due to a uniformly charged rod of length L at a distance x on its perpendicular bisector
We need to calculate the electric field
Using formula of electric field intensity
Where, Q = charge on the rod
The force is on the charged bead of charge q placed in the electric field of field strength E
Using formula of force
Put the value into the formula
We need to calculate the total charge on the rod
Put the value into the formula
Hence, The total charge on the rod is 47.8 nC.
