Your goal is to accelerate the particles to kinetic energy k. what minimum radius r of the cyclotron is required?
densk [106]
Considering the magnetic force is providing the centripetal force,
we get, mv^2/r = qvB
so, r = mv/qB

as the Kinetic energy, K of the particle is given by.5mv^2
so, v = sqrt(2K/m)
substituting the in radius equation,
<span>r = m*sqrt(2K/m)/qB

r = sqrt(2Km)/qB

A particle is moving along a projectile path where the initial height is 96 feet with an initial speed of 16 feet per second.
let's find the  maximum height<span>of the particle

</span><span>s(t)=−16<span>t2</span>+16t+96</span><span>
</span><span>s(1/2)=−16(1/2<span>)2</span>+16(1/2)+96=−16(1/4)+8+96=−4+8+96=100
Therefore the answer is 100
