An object is kept at a distance of 10cm from the mirror.If the object is moved 6cm towards the mirror then the difference of distance of the object and image in 2 cases
An open rectangular tank 1.5 m wide 2m deep and 2m long is half filled with water. It is accelerated horizontally at 3.27 m/sec^2 in the direction of its length. Determine the depth of water at each end of tank. [g = 9.81 m/sec^2]
Show that the following points (3, 2), (3, 2), (1, 2) and (1, 2) taken in order are vertices of a square.
A man weighs 70kg. He stands on a weighting machine in a lift, which is moving (a) Upwards with a uniform speed of 10m/s. (b) Downwards with a uniform acceleration of 5m/s^2. (c) Upwards with a uniform acceleration of 5m/s^2. Take g = 9.8m/s^2. What would be the readings on the scales in each case what would be the reading if the lift mechanism failed and it came down freely under gravity?
A bob of mass m is suspended by inextensible string of length l from a fixed point. The bob is given a speed of at the bottom point. Find the tension in the string when string deflects through an angle 120 degree from vertical.
