firstly there is an error in ques ...in 2nd line unit of wgt is N and that of mass is kg . so i am considering 2 cases :

firstly there is an error in ques ...in 2nd line unit of wgt is N and that of mass is kg . so i am considering 2 cases : case 1 : wgt is supplied

a' = 1/10²m² , w = 50 N •°• P= 50/(1/100) pa =5000pa

case 2

case 2 : mass is supplied

a' = 1/100 , m = 50kg •°• F = 500 N

P = 500*100 pa = 50000pa ...

i hv taken area as a' to avoid confusion with acceleration .. hope it helps ....brother
