Two objects of equal mass rest on the opposite pans of an arm balance. Does the scale remain balance when it is accelerated up or down in a life ?

Two equal masses are kept on the pans of a simple balance in a lift acceleration upward. Then.

Two equal masses each m are hung from a balance whose scale pans differ in vertical height by h . The error in weighing is

Two blocks of equal mass are tied with a light string, which passes over a massless pulley as shown in figure. The magnitude of acceleration of centre of mass of both the blocks is : (neglect friction everywhere)

Assertion : Two bodies of unequal masses m_1 and m_2 are dropped from the same height. If the resistance offered by air to the motion of both bodies is the same, the bodies will reach the earth at the same time. Reason : For equal air resistance, acceleration of fall of masses m_1 and m_2 will be different.

Two equal masses each in are hung from a balance whose scale pans differ in vertical height by h . The error in weighing in terms of density of the earth rho is

Assertion: In projectile motion, the acceleration is constant in both magnitude and direction but the velocity changes in both magnitude and direction. Reason: When a force or accelration is acting in an oblique direction to the direction of velocity then both magnitude and direction of the velocity may be changed.

Assertion : Two similar trains are moving along the equatorial line with the same speed but in opposite direction. They will exert equal pressure on the rails. Reason : In uniform circular motion the magnitude of acceleration remains constant but the direction continuously changes.

An object of mass 5 kg is attached to the hook of a spring balance and the balance is suspended vertically from the roof of a lift. The reading on the spring balance when the lift is going up with an acceleration of 0.25 ms^(-2) is take, (take, g=10ms^(-2) )
