A false balance is such that the bem remains horizontal when the pans are empty . An object weights W1 when placed in one pan and W2 when placed in other pan . The true weight of the object is
A) w1+w2/2
`sqrt w1w2 `
`sqrt (w1^2+ w2 ^2 )`

A body weighs 6gms when placed in one pan and 24gms when placed on the other pan of a false balance. If the beam is horizontal when both the pans are empty, the true weight of the body is :

A body is suspended from a spring balance kept in a satellite. The reading of the balance is W_1 when the satellite goes in an orbit of radius R and is W_2 when it goes in an orbit of radius 2R.

A beam balance of unequal arm length is used by an unscruplus trader. When an object is weighed on left pan. The weight i found to be W_(1) . When the object is weighed on the right plane, the weight is found to be W_(2) . If W_(1) ne W_(2) , the correct weight of the object is

The apparent weight of a man in a lift is w_1 when lift moves upwards with some acceleration and is w_2 when it is accelerating down with same acceleration. Find the true weight of the man and acceleration of lift.

The apparent weight of a man in a lift is W_(1) when lift moves upwards with some acceleration and is W_(2) when it is accerating down with same acceleration. Find the true weight of the man and acceleration of lift .

The Price relative and weight of a set of commoditities are given in the following table If the index for the set is 135 and the sum of the weight is 26, find w_1+ w_2

A body of weight w_(1) when floats in water displaces an amount of water w_(2) . Then w_(1)ltw_(2) . In this statement true or false?

Two weights W_1 and W_2 in equilibrius and at rest are suspended as shown in figure. Then the ratio (W_1)/(W_2) is:

The weight of an object in the coal mine, sea level and at the top of the mountain are W_(1),W_(2) and W_(3) respectively, then

A body of weight w_1 is suspended from the ceiling of a room through as chain of weight w_2 . The ceiling pulls the chain by a force
