Question 1

fundamental forces experienced by quarks

Answer 1

all 4 (only elementary particle that does this)

Question 2

fundamental forces experienced by leptons

Answer 2

all 4 EXCEPT strong nuclear as do NOT contain quarks (electromagnetic e.g. electrons when charged)

Question 3

fundamental forces experienced by mesons

Answer 3

strong, weak and electomagentic as composed of quarks

Question 4

fundamental forces experienced by baryons

Answer 4

all 4 as composed of quarks

Question 5

fundamental forces experienced by gluons

Answer 5

only STRONG

Question 6

calculating baryon number

Answer 6

B = 1/3 * (baryons - antibaryons)
