Answer:
Explanation:
Given that,
Magnetic field, 
Acceleration of the electron, 
Speed of electron, 
The force due to this acceleration is balanced by the magnetic force as :
So, the angle between the electron's velocity and the magnetic field is 10.6 degrees. Hence, this is the required solution,
Answer:
675 Pa.
Explanation:
F = 5+2cos(15t) kN
Area (a) = 8*10-3 m2
Now at t =4 sec
F= 5+2cos(60)
= 5+2*0.5
= 6 kN
Now ,force efficiency is 90%.
Hence,the effectively transmitted force,
Fe = 0.90*6
= 5.4 kN
Hence,pressure is given as,
P = Fe/a
= 5.4*10^3/(8
*10^-3))
P = 675 Pa....answer

Answer:
F = 2.668*10_-6[N]
Explanation:
We can calculate this force using the law of universal gravitation raised by Isaac Newton
![m_{t}=20000[kg]\\m_{c}= 200[kg]\\r = 10[m]\\G = 6.67*10^{-11}[\frac{N*m^{2} }{kg} ] \\](https://tex.z-dn.net/?f=m_%7Bt%7D%3D20000%5Bkg%5D%5C%5Cm_%7Bc%7D%3D%20200%5Bkg%5D%5C%5Cr%20%3D%2010%5Bm%5D%5C%5CG%20%3D%206.67%2A10%5E%7B-11%7D%5B%5Cfrac%7BN%2Am%5E%7B2%7D%20%7D%7Bkg%7D%20%5D%20%5C%5C)
And the force is given by the following expression:
![F=G*\frac{m_{t}*m_{c}}{r^{2} } \\F=6.67*10^{-11} *\frac{20000*200}{10^{2} }\\F=2.668*10^{-6} [N]](https://tex.z-dn.net/?f=F%3DG%2A%5Cfrac%7Bm_%7Bt%7D%2Am_%7Bc%7D%7D%7Br%5E%7B2%7D%20%7D%20%5C%5CF%3D6.67%2A10%5E%7B-11%7D%20%2A%5Cfrac%7B20000%2A200%7D%7B10%5E%7B2%7D%20%7D%5C%5CF%3D2.668%2A10%5E%7B-6%7D%20%5BN%5D)
