Answer 2

Answer:

0.24

Explanation:

Here, m=

u

v

=−4

⇒u=

4

−v

------------(1)

Also, ∣u∣+∣v∣=1.5

4

v

+v=1.5

⇒

4

(v+4v)

=1.5

⇒v=1.2m

So, putting the value of v in equation (1):

u=

4

−1.2

=−0.3m

∴f=

u−v

uv

⇒f=

(−0.3−1.2)

(−0.3×1.2)

=0.24m

Hence the correct option is 0.24
