Answer 1

Answer:

2.75 N

Step-by-step explanation:

Given A tank accelerates upwards with acceleration a = 1m/s² contains water.A block of mass 1 kg and density 0.8 g/cm³ is held stationary inside the tank with the help of a string .The tension in the string will be

So we have g = 10 m/s, a = acceleration = 1m/s^2, density of block = p, density of water = d = 1000 kg /m^3, mass = 1 kg

m/p x d(g + a) = T + m(g + a)

T = m/p x d(g + a) - m(g + a)

 = m/800 x 1000(10 + 1) - m(10 + 1)

= 11000 m /800 - 11 m

= 110 m - 88 m /8

T = 22 / 8

T = 2.75 Newton
