As we know that when charge is released in electric field
It will have two forces on it
1. electrostatic force
2. gravitational force
now if the ball will accelerate upwards so we can say
net upward force = mass * acceleration
now we can find charge q on it by above equation
So above is the charge on the particle
Answer:
<h2><u>
sun generates energy from a process called nuclear fusion.</u></h2>
Explanation:
<u>During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released</u>
<u>Hope this help:)</u>
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

u

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Answer: 24.39 N
Explanation:
Given
Torque required to open the lid is
diameter of lid
Force exerted by fingers and thumb forms a couple. So, torque can be written as
Thus, the magnitue of each force is 24.39 N
