(i) (-8m, 7m), |
(ii) (7m, - 3m) and |
(iii) (-7m, 3m) |
Which pair gives the negative displacement? |
A) (i)
B) (ii)
C) (iii)
D) (i) and (ii)
Correct Answer: B
Solution :
The displacement of the man from A to E is \[\Delta x={{x}_{2}}-{{x}_{1}}=7m-\left( -8m \right)=+15\text{ }m\] directed in the positive x-direction. (ii) The displacement of the man from E to C is \[\Delta x=-\,3\,m-\left( 7m \right)=-10\text{ }m\] directed in the negative x-direction. (iii) The displacement of the man from B to D is \[\Delta x=3m-\left( -7m \right)=+10\text{ }m\] directed in the positive x-axis.You need to login to perform this action.
