Physics Why the needle of iron swims on water surface when it is kept gently ? Due to surface tension It will remain under the water, when it will displace more water than its weight Due to its shape The density of needle is less than that of water Due to surface tension It will remain under the water, when it will displace more water than its weight Due to its shape The density of needle is less than that of water ANSWER DOWNLOAD EXAMIANS APP
