1)a=f/m
a=200/16
a=12.5m/s

2)t=m×a
t=16×10 (g=10)(approx)
t=160 newton

3)t=7×10
t=70 newton

(for any step that u have not understood plus comment I will try to explain)

SumanSekhar: weight

SumanSekhar: mg

tony19: ma mein m means mass

SumanSekhar: yes

tony19: Then why do u want to add weight to ma?

SumanSekhar: a means the acceleration of th total system.

tony19: If a is the acceleration due to gravity then ma means mg

tony19: I still did not get why t= w+ma?????

nitilchauhan: Force and tension formula are same means if f=ma then tensin=ma

tony19: That is what i m saying
T= ma or mg
