13Negative mass is an existing concept (Google it out..) .... but i dunno how n why it comes in here...
1well even two positive masses attract each other.
so you could say air has positive mass so both attract each other.
in short either there must be a mis-print or the source is crap
13Yeah...tht was wht i thot of ; but the explaination confused me...
Wht strikes my mind is tht he says -
A Lighter body inside a denser medium behaves like a -ve mass ,,,,
Wht if v had a huge air bubble & an iron piece inside water ??
Won't they attract each other?? (however feeble the force may be...)
