Hope it helps. Plz mark me brainliest.

Answer 2

Question 1

Answer : (c) Twice as much

Explanation : The weight of truck is more than the weight of car, so the acceleration of the car is more because of less weight

Question 2

Answer : (d) Between 1N and 7N

Explanation : A particle is simultaneously acted by two forces equal to 4N and 3N. The net force on the particle is. i.e., net force on the particle is between 1N and 7N.

Question 3

Answer : (c) P

Explanation :

= √ P^2 + P^2 + 2P^2 × cos120

= √2P^2 + 2P^2×(-1/2)

= √2P^2 - P^2

= √P^2

= P
