Question

A body of mass 30 kg stands on a weighing machine lying on floor of a lift. what will be the weight of the body when lift moves upward with an acceleration =2.2m/s2

Answer 1

Answer:

N =ma+mg

here we have mass =30 kg

a= 2.2m/sec2

ang mg (gravitational force take 10 m/s2)

w=m(a+g)

w=30 x2. 2+ 30 x 10

66+300

= 366 N

Answer 2

Answer:

Explanation:

Answer:

N =ma+mg

here we have mass =30 kg

a= 2.2m/sec2

ang mg (gravitational force take 10 m/s2)

w=m(a+g)

w=30 x2. 2+ 30 x 10

66+300

= 366 N
