Answer questions on resultante of non-linear Activity
forcos
The forces act on an object. The first is a horizontal 50 N force. The
second is a 40 N force acting at an angle to the horizontal
Use a graphical method drawn to a scale of 1mm :1N to find the
resultant at the 40N force is inclined at
1.11 30° to the horizontal
1.1.2 60° to the horizontal​

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
