Answer:
Electron must be placed at a distance of 2.69 ×10^5 m in the direction of positive y-axis.
Explanation:
Charge on electron = e = -1.6 × 10^-19 C
Mass of electron = m = 9.1 × 10^-31 kg
Charge at origin = q = -0.45 nC
According to given condition in the question:
Fe = Fg
kq1q2/r^2 = mg
(9 × 10^9)( -1.6 × 10^-19)( -0.45n)/r^2 = (9.1 × 10^-31)(9.8)
r = √7.2 ×10^10
r = 2.69 ×10^5 m in the positive y-axis direction
Explanation:
The faster a stream flows, the larger the size of particles it is able to transport.
Fast moving stream due to their velocity and momentum can exert more force and impact larger materials more causing them to move readily.
- The faster the speed of stream the larger the size of sediment it is able to transport.
- This why the edges of oceans contains very coarse particles whereas the still deeper waters are made up of fines.
- A stream is able to transport sediments in three forms:
- As solution in dissolved forms
- As bedload which made up of large boulders.
- As suspension

Answer:<em> inversely proportional to </em>
The work relates the displacement and Force
W = F. d Joules
Where W= work,
F = Force ,
d = displacement of object
From the above equation
<em> force and displacement are inversely proportional </em> and work and force are directly proportional
The temperature of both the halves of the body remain same and thus the body remain in thermal equilibrium.
Both the parts of the body even after being in contact with each other will not transfer heat and thus maintain equal temperature and the resultant of the two will be zero.
