d = distance between the two point charges = 60 cm = 0.60 m
r = distance of the location of point "a" where the electric field is zero from charge 
between the two charges.
= magnitude of charge on one charge
= magnitude of charge on other charge
= 3
= Electric field by charge at point "a"
= Electric field by charge at point "a"
Electric field by charge at point "a" is given as
= k /r²
Electric field by charge at point "a" is given as
= k /(d-r)²
For the electric field to be zero at point "a"
=
k /(d-r)² = k /r²
/(d-r)² = 3 /r²
1/(0.60 - r)² = 3 /r²
r = 0.38 m
r = 38 cm
Answer:
Case Study: General Andrew Jackson: Andrew Jackson's military career spanned several wars including the American Revolution, the Creek War, the War of 1812, and the First Seminole War. After the Creek War, Jackson and the Creek Indians signed the
Answer:
41.07 m
Explanation:
According to the data:
Velocity = 2.65 m/s
Time = 15.5 s
Now the formula to calculate the distance is
Distance = Velocity x Time
Distance = 2.65 x 15.5
Distance = 41.07 meter
Kindly note that the person suddenly started to run at the velocity which is mentioned later that is 2.65 m/s.So the velocity given before is just ignored and we don't have to use any of the three equations of motion of kinematics.
The initial velocity is obtained as 2.5 m/s.
<h3>What is the initial speed?</h3>
To obtain the initial speed, we have to apply the law of conservation of linear momentum which states that momentum before collision is equal to momentum after collision.
Now, the two fragments initially had one velocity before they were split in two directions opposite each other;
Applying the principle of conservation of linear momentum to this problem;
(2 + 10)v = (6 * 10) - (2 * 15) (they moved in opposite directions)
12v =60 - 30
12v = 30
v = 30/12
v = 2.5 m/s
