Question

# Observe the following statements and choose correct answer

Statement-I:A particle p moves along a straight line, starting from a fixed point ‘O’, obeying s=16+48t-the direction of p when t=5 is along

Statement-II: For a particle moving on a line, if velocity v<0 then the body moves towards the initial point.

- I,II are true, II is correct explanation of I
- I,II are true, II is not correct explanation of I
- I is correct II is false
- I is false II is true

## The correct answer is: I,II are true, II is not correct explanation of I

### Divide the following fractions:

Here, we have to divide the given fractions.

Now, 2/11 ÷ 9/22

= 2/11 × 22/9

= 2/1 × 2/9

= 2 × 2 / 1 × 9

= 4/9

Hence, the correct option is (a).

Now, 2/11 ÷ 9/22

= 2/11 × 22/9

= 2/1 × 2/9

= 2 × 2 / 1 × 9

= 4/9

Hence, the correct option is (a).
