The threshold energy to initiate a certain nuclear reaction is 3.16 MeV and the Q for the reaction is -2.37 MeV. The stationary target is how many times as massive as the incident particle?

What will be an ideal response?

Question 2

A long line of charge with charge per unit length 1 is located on the x-axis and another long line of charge with charge per unit length 2 is located on the y-axis with their centers crossing at the origin.

In what direction is the electric field at point z = a on the positive z-axis if 1 and 2 are positive? A)

the positive z-direction
B)

halfway between the x-direction and the y-direction
C)

the negative z-direction
D)

all directions are possible parallel to the x-y plane
E)

cannot be determined
