Question

5. A 20kg box is pulled up on a slope with a
constant speed to a distance of 4 mts raising
it to a height of 2 mts above its starting point,
the force F that exerted on the box is:
(a) 50 N
(b) 100 N
(c) 150 N
(d) 200 N
tin field in a long straight solenoid is:​

Answer 1

Answer:

b) 100N

Explanation:

sinθ=2/4=1/2

g=10m/s

as the object moves with constant velocity, net force on the box is 0

the force exerted = gravitational force acting on it

F=mgsinθ=20*10*1/2=100N
