Answer 1

Answer:

write your question properly i can't understand your question properly

Answer 2

First of all we find F1=mg ,

F1=10×9.8N F1=98N.

this is the grvitional force.so we can say that this is the weight of the object.

but in case of vacuum this will be changed.

we take X N as force in vacuum and a=3m\s^2

and mass is 10kg so X=30N

This is F2

F=F1-F2

F=(98-30)N

F=68N

Explanation:

hey we can do it directly with the formula

force=mass X acceleration

and also f = mg

finally to get force subtract F2 from F1

BOOM HERE'S YOUR ANSWER

but I would say options given are wrong
