not that i can't solve,i hav already solve 4 d resultant to be 21.8N.after using cosine rule.. But am confused in solving for the equilibrant dat is the B parts of d question Mr bobpursley,how can i get the equilibrant.
d question is not complete.either d (specific heat capacity of ice) is give or(specific heat of fusion of ice)is given so check d question.
From electric field force b/w two charges=F=Q1Q2/4pieE¤r (square) force(f)=197,Q1=50,Q2=50,and 4pie E¤r(square)=8.98755*109Nm/C :-> 197=50*50 /8.98755*109*r 197*8.98755*109*r2=50.0*50.0 r2=192730.912/2500 after division then take d square root of d ans.
