The kinetic energy (KE) is 250 J and the gravitational potential energy (GPE) is 392 J
It is 72 km/h
I hope it helps
Answer:
<h2> r=mv/Be</h2>
Explanation:
If a positive charge enters a magnetic field at 90 degrees the charge is deflected in a circular path by a force that acts perpendicular to it in line with Flemings right-hand rule
to derive the radius of the path of the charge we apply
F= mv^2/r=Bev
where
m= mass of the electronic charge
e=charge
B=magnetic field
v=average speed
r=radius
rearranging we have
r=mv^2/Bev
r=mv/Be
Answer:
positive degree:
No other peak of the Himalayas is as high as Mount everest
It’s definitely the 3rd one
