Question

plz solve the attached question it is very urgent​

Answer 1

Answer:

35 N

Explanation:

Force on 2 kg block provides acceleration

$2a = 0.3 \times 2 \times 10 \\ a = 3 \frac{m}{ {s}^{2} }$

Force on block 5 kg

Friction Force due to block 2 kg and due to surface both acted in opposite direction

$f - (7 \times 10 \times 0.2) - (0.3 \times 2 \times 10) = 5a \\ f - 14 - 6 = 5 \times 3 \\ f = 20 + 15 \\ f = 35$
