here comes the ans:-

first one can be written as =

-4i +7j

other one can be written as in vectorial form like=

1 +5j

there by by adding the both we have displacement like=

AS WE ALL KNOW DISPLACEMENT IS THE VECTOR QUANTITY AND THERE BY IT'S MAGNITUDE GETS NEGATIVE SIGN WHERE AS THE DIRACTION IS REVERSED SO FOR TO GET VECTORS IN SAME DIRECTION WE CAN WRITE AS --------

-4. ------> VECTOR IN OPPOSITE DIRECTION

BY REVERSING VECTOR DIRECTION WE GET AS =

4 AS MAGNITUDE...

and we can write the magnitude of displacement to get distance so it becomes=

dis=√(5)² +(12)²

dis= √ 25+ 144

so final distance becomes=

√ 169. = 13

,------> brainliest the ans please ☺

kunala87: bt the final is nt correct according to the options..
sahil1531: bro options are?
kunala87: a.root 13,b. root 14 ,c. 13 , d.14
sahil1531: c must be correct than bro ☺
sahil1531: know see tha ans ☺☺
sahil1531: and please brainliest it☺
kunala87: ok
