B)



SEEN FROM THE FIGURE THE ACC OF 2KG BLOCK IS TWICE THAT OF THE 5KG BLOCK


 


LET THE ACC OF THE 5 KG BLOCK BE A THEN THAT OF 2KG BLOCK IS 2A



5G-2T=5A   (2T SINCE IT IS CONNECTED BY 2 STRINGS)



T=2(2A)



T=4A



5G=13A



A=5G/13



THIS IS THE ACC OF THE 5 KG BLOCK



THE ACC OF 2 KG BLOCK IS 10/13 G



PLZ RATE ME IF U FIND ME USEFUL



!!!!!!CHEERS!!!!!!!!!!


From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king.
